* Breakdown tool for Poses (Shift-E in PoseMode) now works. Now this works as a modal operator when invoked, with the horizontal movement of the mouse (left to right) corresponding the placement of the breakdown relative to the endpoint keyframes.
* Moving bones between armature layers in Edit Mode didn't work (wrong variable name used)
* Fixed several notifier-related bugs regarding editing armature settings and the 3d-view not refreshing
* Duplicating bones preserves the rotation mode
* Animation Data for Nodes is now show in Datablocks viewer (i.e. AnimData for NodeTrees has now been wrapped)
