* Moves uploaded files from temporary upload folder to a specified new folder.

*
* 1. Set the temporary upload folder
* <code>
* plugin.Tx_Formhandler.settings.files.tmpUploadFolder = uploads/formhandler/tmp
* </code>
*
* 2. Set the folder to move the files to after submission
* <code>
* plugin.Tx_Formhandler.settings.finishers.1.class = Tx_Formhandler_Finisher_StoreUploadedFiles
* plugin.Tx_Formhandler.settings.finishers.1.config.finishedUploadFolder = uploads/formhandler/finishedFiles/
* plugin.Tx_Formhandler.settings.finishers.1.config.renameScheme = [filename]_[md5]_[time]
