2.5 - Pose Enhancement Tools

This commit restores the 'Relax Pose' tool, and also introduces two others: 'Push Pose' and 'Pose Breakdowner'.
Be aware that this commit is just the initial starting point, with some parts yet to be done.

A short description of these tools follows:
* Relax Pose (Alt-E) - makes the current pose more like the poses on either side of it
* Push Pose (Ctrl-E) - exaggerates the current pose
* Breakdowner (Shift-E)[not working yet] - when this works, it will allow for interactive selection of a good in-between pose to act as a breakdown. 

Todo's:
* Connect up the 'percentage' slider in the operator settings to allow these effects to be dialed in/out, exaggerating/relaxing/moveing-between-keyframes by varying degrees until the desired effect is reached.
* Allow these effects to be interactively dialed in/out. The idea is to use the mouse to interactively set the percentage slider value initially, then use the percentage slider to tweak later.
* Figure out why breakdown breaks down
