Update to allow setting start date

Hi Marcus,

Thanks for the great plugin.

I wanted to be able to set the start date to show a calendar a few months in advance…
It looks like there was some code in your wrapper to do this but that was for v1 (month and year parameters are no longer supported in v2): http://fullcalendar.io/wiki/Upgrading-to-v2/

Anyway I’ve hacked the code to add this functionality by using a shortcode… It’s a pretty simple change – the diffs are below:
