[dev] Patch for kronolith legends

[Jason Rust]

Attached is a patch that implements a category legend for the different
calendars displayed.  This allows the user to know what a color for a
category means when viewing the month/day/week view (idea was taken from
the imp legend)

I also found that there is no way for a user to have more than 1 legend
even if the user has created 2 different calendars.  I'm thinking that
the category editor in kronolith should dynamically load a different
legend when the calendar is changed (via a select box).  The
functionality would be similar to the calendar editor.  Does this sound
like the correct way to go about implementing this functionality?
