Code review comment for lp:~renatofilho/indicator-datetime/calendars

I guess it would help if we hadn't sat on this MP for 8 months, but the datetime codebase has changed so much that this MP can't work as-is.

The idea is fine though and I've opened a new ticket to track it. https://bugs.launchpad.net/indicator-datetime/+bug/1206942

If you want to update this MP for the 13.10 refactoring of i-datetime, please assign yourself to that ticket and I'll review sooner rather than later.
