* Apr 13/2004: Niels Leenheer                                                   *
* Large rewrite to ensure the calender only uses one query to fetch all events  *
* instead of one query for each day. This reduces the number of queries by      *
* 27 or 34. Also, multiple bugs are fixed such as:                              *
* - Multiple events on the same say are now properly shown                      *
* - If there were multiple events on the same day and the first event was       *
*   off limits for the current user, the other events were not taken into       *
*   acount, and as a result that day was not marked as a day with an event      *
* - Weekday abbreviations are now displayed according to the current locale     *
* - Removed <html> and <body> tags from the output, because the output is used  *
*   in an already existing html document.                                       *
*                                                                               *
* Mar 29/2006: Blaine Lang    ( mycal version 1.5 )                             *
* Updated for Geeklog Version 1.4                                               *
*                                                                               *
* Jun 16/2006: Komma Tetsuko (for japanese)                                     *
* Oct 22/2006: mystral-kk - a minor bug fix                                     *
