Video Pornster updated to v2.2.1

= 2.2.1 Released April 24th, 2015 =

* Vulnerability fix for add_query_args in PUC module.

This was to address the XSS Vulnerability with versions of WordPress earlier than 4.2.

In truth, the functions involved were only called internally by Video Pornster with static urls for our plugin update checker, so no vulnerability was actually possible. Still, best to address it.
