/** quick and dirty logfile viewer
*
* this constructs a table of the HTML-variety with the contents of the logtable.
* fields displayed are: datim, IP-address, username, logpriority and message
* we use a LEFT JOIN in order to get to a meaningful username rather than a numeric user_id
* an attempt is made to start with the last page of the logs because that would probably
* be the most interesting part. We paginate the log in order to keep it manageable.
*
* <Rant><br>
* I used to use the built-in constants like LOG_INFO and LOG_DEBUG to allow for different levels
* of logging (see {@link logger()}). To my complete surprise logging didn't work at all on
* Windows (it did on Linux). The reason was that LOG_DEBUG and LOG_INFO and LOG_NOTICE are all
* defined to be the same value. WTF? Any test based on LOG_DEBUG and LOG_INFO being different
* would fail, hence no logging at all. The mind boggles! So, instead of using built-in constants
* I had to define my own and do a global search&replace. Aaarghhhhhh!!!!<br>
* </Rant><br>
*
* @param object &$output collects output to show to user
* @return void output displayed via $output
* @todo should we allow for fancy selection mechanisms on the logfile or is that over the top?

* . navigation link to the parent directory

* . 0, 1 or more rows with a checkbox and delete and preview links to files (if any)
* . (optional) a 'select all' checkbox
* - (optional) Delete-button to mass-delete files
*
* The table can be ordered in various ways: by name, by size and by date,
* either ascending or descending. Clicking the relevant column header yields
* another sort order. This toggles between ascending and descending.
* Default sort order is by name ascending.
*
* The checkbox 'select all' works with Javascript in the most simple way:
* an ad-hoc script connected to the onclick attribute of the select all checkbox.
* However, the select all checkbox itself is rendered via Javascript.
* The effect is that this feature is only available if Javascript is enabled
* in the browser. If it isn't, no select all is visible so it can not distract
* the user. This is part of the attempt to make this CMS usable even without
* Javascript.
