/**
* Upgrade or patch the database with a selected upgrade/patch file.
*
* The following "functions" within the selected file will be processed:
*
* #IfNotTable
*   argument: table_name
*   behavior: if the table_name does not exist,  the block will be executed
*
* #IfTable
*   argument: table_name
*   behavior: if the table_name does exist, the block will be executed
*
* #IfColumn
*   arguments: table_name colname
*   behavior:  if the table and column exist,  the block will be executed
*
* #IfMissingColumn
*   arguments: table_name colname
*   behavior:  if the table exists but the column does not,  the block will be executed
*
* #IfNotColumnType
*   arguments: table_name colname value
*   behavior:  If the table table_name does not have a column colname with a data type equal to value, then the block will be executed
*
* #IfNotRow
*   arguments: table_name colname value
*   behavior:  If the table table_name does not have a row where colname = value, the block will be executed.
*
* #IfNotRow2D
*   arguments: table_name colname value colname2 value2
*   behavior:  If the table table_name does not have a row where colname = value AND colname2 = value2, the block will be executed.
*
* #IfNotRow3D
*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  If the table table_name does not have a row where colname = value AND colname2 = value2 AND colname3 = value3, the block will be executed.
*
* #IfNotRow4D
*   arguments: table_name colname value colname2 value2 colname3 value3 colname4 value4
*   behavior:  If the table table_name does not have a row where colname = value AND colname2 = value2 AND colname3 = value3 AND colname4 = value4, the block will be executed.
*
* #IfNotRow2Dx2
*   desc:      This is a very specialized function to allow adding items to the list_options table to avoid both redundant option_id and title in each element.
*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  The block will be executed if both statements below are true:
*              1) The table table_name does not have a row where colname = value AND colname2 = value2.
*              2) The table table_name does not have a row where colname = value AND colname3 = value3.
*
* #IfRow2D
*   arguments: table_name colname value colname2 value2
*   behavior:  If the table table_name does have a row where colname = value AND colname2 = value2, the block will be executed.
*   
* #IfRow3D
*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  If the table table_name does have a row where colname = value AND colname2 = value2 AND colname3 = value3, the block will be executed.   
*
* #IfIndex
*   desc:      This function is most often used for dropping of indexes/keys.
*   arguments: table_name colname
*   behavior:  If the table and index exist the relevant statements are executed, otherwise not.
*
* #IfNotIndex
*   desc:      This function will allow adding of indexes/keys.
*   arguments: table_name colname
*   behavior:  If the index does not exist, it will be created
*
* #IfNotMigrateClickOptions
*   Custom function for the importing of the Clickoptions settings (if exist) from the codebase into the database
*
* #IfNotListOccupation
* Custom function for creating Occupation List
* 
* #IfNotListReaction
* Custom function for creating Reaction List
*
* #IfTextNullFixNeeded
*   desc: convert all text fields without default null to have default null.
*   arguments: none
* 
* #IfTableEngine
*   desc:      Execute SQL if the table has been created with given engine specified.
*   arguments: table_name engine
*   behavior:  Use when engine conversion requires more than one ALTER TABLE
*
* #IfInnoDBMigrationNeeded
*   desc: find all MyISAM tables and convert them to InnoDB.
*   arguments: none
*   behavior: can take a long time.
* 
* #EndIf
*   all blocks are terminated with a #EndIf statement.

* The following "functions" within the selected file will be processed:
*
* #IfNotTable
*   argument: table_name

*   arguments: table_name colname
*   behavior:  if the table exists but the column does not,  the block will be executed
*
* #IfNotColumnType
*   arguments: table_name colname value
*   behavior:  If the table table_name does not have a column colname with a data type equal to value, then the block will be executed
*
* #IfNotRow
*   arguments: table_name colname value
*   behavior:  If the table table_name does not have a row where colname = value, the block will be executed.
*
* #IfNotRow2D

*   behavior:  If the table table_name does not have a row where colname = value AND colname2 = value2 AND colname3 = value3 AND colname4 = value4, the block will be executed.
*
* #IfNotRow2Dx2
*   desc:      This is a very specialized function to allow adding items to the list_options table to avoid both redundant option_id and title in each element.
*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  The block will be executed if both statements below are true:
*              1) The table table_name does not have a row where colname = value AND colname2 = value2.
*              2) The table table_name does not have a row where colname = value AND colname3 = value3.

*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  If the table table_name does have a row where colname = value AND colname2 = value2 AND colname3 = value3, the block will be executed.   
*
* #IfIndex
*   desc:      This function is most often used for dropping of indexes/keys.
*   arguments: table_name colname
*   behavior:  If the table and index exist the relevant statements are executed, otherwise not.
*
* #IfNotIndex
*   desc:      This function will allow adding of indexes/keys.
*   arguments: table_name colname
*   behavior:  If the index does not exist, it will be created

*   Custom function for the importing of the Clickoptions settings (if exist) from the codebase into the database
*
* #IfNotListOccupation
* Custom function for creating Occupation List
* 
* #IfNotListReaction
* Custom function for creating Reaction List
*
* #IfTextNullFixNeeded
*   desc: convert all text fields without default null to have default null.
*   arguments: none
* 
* #IfTableEngine
*   desc:      Execute SQL if the table has been created with given engine specified.
*   arguments: table_name engine
*   behavior:  Use when engine conversion requires more than one ALTER TABLE
*
* #IfInnoDBMigrationNeeded
*   desc: find all MyISAM tables and convert them to InnoDB.
*   arguments: none

*
* #IfNotRow2Dx2
*   desc:      This is a very specialized function to allow adding items to the list_options table to avoid both redundant option_id and title in each element.
*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  The block will be executed if both statements below are true:
*              1) The table table_name does not have a row where colname = value AND colname2 = value2.
*              2) The table table_name does not have a row where colname = value AND colname3 = value3.

*   behavior:  If the table table_name does have a row where colname = value AND colname2 = value2, the block will be executed.
*
* #IfIndex
*   desc:      This function is most often used for dropping of indexes/keys.
*   arguments: table_name colname
*   behavior:  If the table and index exist the relevant statements are executed, otherwise not.
*
* #IfNotIndex
*   desc:      This function will allow adding of indexes/keys.
*   arguments: table_name colname

*   arguments: table_name colname value colname2 value2 colname3 value3
*   behavior:  The block will be executed if both statements below are true:
*              1) The table table_name does not have a row where colname = value AND colname2 = value2.
*              2) The table table_name does not have a row where colname = value AND colname3 = value3.
