Bugfixes:

* The python 'math' library is now included in the py-namespace used to evaluate button expressions. So it is now possible to do 'radians(somevalue)' to get a rotation value that Blender can understand...

* Shapekey path getting function now uses the appropriate wrapper for grabbing the pointer to the ID block for the ShapeKey

* Made the Graph Editor's minimum zoom size finer...
