Cleanup FWL Event and Message code.

This CL removes any CFWL_Evt classes for which nothing was listening to the
events. For events with no parameters the override class was removed and
the event type passed into CFWL_Event which is used instead. Any event or
message parameters which are un-read have been removed.
