== IPO Copy/Paste ==

Browse Source 
When in EditMode for IPO-curves, keyframes are now pasted from the IPO-editor's copy/paste buffer instead of the entire curves being pasted. This makes it possible to 'move' keyframes from one IPO-curve to another. 

* Only keyframes in the copy/paste buffer that are selected, are pasted
* All keyframes that are pasted, are pasted relative to the current frame, with the current frame being the location of the first pasted keyframe.
* Pasted keyframes replace exisitng keyframes if they occur at the same location.
