Calendar events applet

A self contained applet that displays public events from the relevant Google Calendar based on the users LC_TIME value.

Users are also able to add links to their personal Google Calendars, and the parsing framework is written to allow for multiple sources to be added in the future.

Personal settings are stored in ~/.cinnamon/uuid/

The applet purposefully doesn't conflict with calendar@cinnamon.org in order to provide a choice for the end user.
