[kronolith] Categories for remote calendars

[Justus Pendleton]

Hi,

I recently started playing around with Kronolith's remote calendar
support by adding a bunch of calendars from www.icalshare.com.  All
was pretty much well except for one thing, all of the events showed up
as unfiled and thus had the same color making them hard (for me, at
least) to differentiate in the calendar views.  I thought it would be
nice to allow the user to specify a category for all events in a
remote calendar.

So I tried to make a few changes toward that end.  I have attached a
patch showing what I've done.  All is pretty much well with one
caveat:

Warnings are generated by preexisting remote calendars on account
of them not having this new category defined.  This is the first time
I've ever written any PHP so I wasn't sure how to go about avoiding
that warning.

I haven't used remote calendars much so I don't know if this is a
good way to handle them or not.  But below is my patch to add this to
Kronolith.
