!!!Revisions
<<<
2011.01.04 1.5.1 corrected parameter handling for {{{<<calendar year>>}}} to show entire year instead of just first month.  In createCalendarMonthHeader(), fixed next/previous month year calculation (use parseInt() to convert to numeric value).  Code reduction (setting options).
2009.04.31 1.5.0 rewrote onClickCalendarDate() (popup handler) and added config.options.txtCalendarReminderTags.  Partial code reduction/cleanup.  Assigned true version number (1.5.0)
2008.09.10 added '+n' (and '-n') param to permit display of relative months (e.g., '+6' means 'six months from now', '-3' means 'three months ago'.  Based on suggestion from Jean.
2008.06.17 added support for config.macros.calendar.todaybg
2008.02.27 in handler(), DON'T set hard-coded default date format, so that *customized* value (pre-defined in config.macros.calendar.journalDateFmt is used.
2008.02.17 in createCalendarYear(), fix next/previous year calculation (use parseInt() to convert to numeric value).  Also, use journalDateFmt for date linking when NOT using [[DatePlugin]].
2008.02.16 in createCalendarDay(), week numbers now created as TiddlyLinks, allowing quick creation/navigation to 'weekly' journals (based on request from Kashgarinn)
2008.01.08 in createCalendarMonthHeader(), 'month year' heading is now created as TiddlyLink, allowing quick creation/navigation to 'month-at-a-time' journals
2007.11.30 added 'return false' to onclick handlers (prevent IE from opening blank pages)
2006.08.23 added handling for weeknumbers (code supplied by Martin Budden (see 'wn**' comment marks).  Also, incorporated updated by Jeremy Sheeley to add caching for reminders (see [[ReminderMacros]], if installed)
2005.10.30 in config.macros.calendar.handler(), use 'tbody' element for IE compatibility.  Also, fix year calculation for IE's getYear() function (which returns '2005' instead of '105'). Also, in createCalendarDays(), use showDate() function (see [[DatePlugin]], if installed) to render autostyled date with linked popup.  Updated calendar stylesheet definition: use .calendar class-specific selectors, add text centering and margin settings
2006.05.29 added journalDateFmt handling
