* Relax and Push are now interactive. Moving the mouse left<->right decreases/increases (respectively) the number of times the pose is relaxed or pushed. The sensitivity on this could be tweaked as necessary.
* Cancelling these 'pose sliding' tools now correctly restores the initial pose
* Autokeyframing is now only done when the operator is confirmed.

Also, made 'View persp/ortho' <-> 'View Persp/Ortho' to be more in line with other operator names, but to also make it easier to read.
