Updated PyroCMS version to 2.2

This got reverted in the merge.

I also switched any references to use `{{ variables:get_var
name='pyrocms_version' }}` instead. This allows the one place of
changing it in the config.

 ## Documentation
 Having a good API documentation is a vital requirement for any successful project. When building your module, please take the time to document its code or even write help articles on it (but that is a different story). 
 
-Most of PyroCMS' core components [are documented](http://docs.pyrocms.com/2.1/api/) and add-ons are actually expected to keep up by at least having each of their files declare the respective package they belong to. Anything can be documented except for views. Classes and functions should be documented using the standard PHPDoc format.
