The tests weren't complete nor were they being used so I dropped them. Since
this branch is still actively being maintained as it's the PHP 5.3 compatible
stuff I figured I should update the headers to have the current year and
explicitly show that it's PHP 5.3+ and not just PHP 5.
* Uncommented the return type logic in the controller and implemented it (no sanity checking on if the return type is valid as per the module)
* Cleaned up some @todo's in the Controller class
* Added the XML Display class
