ui-calendar ~0.9.0 does not handle recerrent events.

[pavlov99]

Dear team!

I have used 3 different angular-ui-calendar versions:

• 0.8.1 (current bower version)
• 0.9.0-beta.1 (latest bower version)
• source from this repository

Version 0.8.1 does not handle language. In demo example if I change to Hungarian, calendar disappears and I need to refresh the page. If I change date for recurrent event, it works well.

Versions 0.9.0-beta.1 and src/calendar.js both work with language, but if I change first recurrent event, secound is not changed. So, it is bossible to change recrrent events independently.

In both cases I have used demo example from this repository.
Could you fix recurrent events processing, please.

this PR needs to be fixed up some, but it should fix this issue #171
