calendar 7.x-3.3

======================
Version 7.x-3.3
======================

NEW FEATURES:
- An option to add Colorbox settings to the calendar template has been added to admin/config/date/calendar.
- The template has been updated to add the Colorbox settings if the option to use them has been selected and Colorbox is enabled.
- The theming has been altered a bit to make sure that you can display a rendered entity in a Colorbox field.
- A new calendar style option has been added to choose fields to exclude from multi-day rows, so multi-day rows can be set up to display only the Colorbox picker.
