This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
E.g. for Easter, and entries like "04/SunFirst" calendar will
now report:
04/05* Good Friday (2 days before easter)
04/07* First Sunday...
instead of:
Easter-2 Good Friday...
04/SunFirst First Sunday...
I also modified the calendar files to use the variable day format
for a lot of events so that they will be reported correctly.
E.g. U.S. daylight savings time is now listed as:
04/SunFirst Daylight savings time...
There are still a lot of wrong dates in there for some events
that move from year to year, but I don't have a good calendar handy
right now that I can use for reference.
