2.5 - Context API access for Bones (EditMode and PoseMode)

* Added selected, selected+editable, and active to access EditBones for Armature Operators to use. These take into account X-Axis Mirror too, so there is really no need to check that sort of thing anymore in tools. 

* Added a quick testing operator for verifying that these loops filter the data correctly. I've dumped this in armature_ops.c for now. It can be activated using the TKEY hotkey in Armature EditMode only. This should be removed once we have a few more functional tools.

* Ported over cleaned up roll-calculation tools from AnimSys2
* Removed a few ugly stubs from posemode code
