board index. It uses just the following functions:
void BoardIndex()
- shows the board index.
- uses the BoardIndex template, and main sub template.
- may use the boardindex subtemplate for wireless support.
- is accessed by ?action=boardindex.
bool calendarDoIndex()
- prepares the calendar data for the board index.
- takes care of caching it for speed.
- depends upon these settings: cal_showeventsonindex,
cal_showbdaysonindex, cal_showholidaysonindex.
- returns whether there is anything to display.
