NLA SoC: Transform Code for NLA-Strips recoded (still buggy)

Recoded the Transform code for NLA-Strips so that they can now be moved between strips and will not get truncated when they get moved into other non-moving strips. 

Todos:
* The current code for moving strips between tracks is buggy (only goes up, and has a tendency to move up without being told to)
* Auto-snapping doesn't work yet...
