The basic calendar object (iCalObject) can already store categories.
The only thing missing should be the user interface.  This of course
needs tweaking of the event-edit dialog.

However, we *really* need a way to share categories between gnomecal
and gnomecard.  Eric already added support for categories in
gnomecard.

I would like to make some important changes to gnomecal that are not
entirely related to this:

	1. Gnomecal needs to be converted to use UTC internally
           instead of localtime.  This will let us handle multiple
           calendars with different time zones correctly.

	2. The recurrence engine is horrible.  It needs to be
           rewritten in terms of "add days" and "subtract dates"
           instead of generating events by brute force and putting
           them in a list.

	3. Maybe (2) can be done with GDate's help (this is Glib's
           date manipulation functions), I'm not sure.
