2.5 Action Editor - Big WIP Commit

* Brought back backend for editing keyframes IPO/IPO-Curves. Did some refactoring work here that will still have to be verified when operators using them are added.

* Animation channel filtering code now returns the number of channels filtered (for Action Editor to set totrect of channels - TODO still!)

* View2D - made function to check if mouse is in View2D scrollers an API function

* Renamed keyframe related files. The old names were too clumsy.

* Started porting click-select operators for Action Editor. These don't work currently, as the events are being stolen by the markers. This needs to be fixed ASAP.
