calendar 6.x-2.0-rc5

Version 2.0 rc5
=================
Note:

The Day and Week templates have changed, so custom themes may need to be updated.
The new templates create an agenda-style display where events are grouped by hour.

New Features:
=============
- Update day and week view to use new configurable, agenda-style calendar views grouped by hour.
- #337004 By hotspoons: Add settings to display calendar legend colors based on taxonomy.
- #319344 By MothersClick.com: Add updated css styles, settings to truncate titles in calendar cells
and limit the number of events that display in calendar cells.
- Make default calendar view configurable so we can create default calendars for specific date fields.
- Add a date_embed_view() function to provide a way to embed views and have their navigation move
either together or separately, and document it in Advanced help.
- Start building Advanced help instructions, including how to do iCal import using Feed API.
