[Bf-taskforce25] Blender spring cleaning

[bassam]

sorry, -1 on autoIK: autoIK is really dangerous, can break many rigs,
and should only be disabled by default.
autoIK can move bones that are hidden/not intended to be moved by the
animator. 

+1 on bbone rest: this is just a sane normal behavior.
+1 on stride root, I think that will go away anyway.
+1 on W (wireframe bones) it should just work with an edge only object,
just like objects do.


sorry, had to weigh in on Cessen's armature notes.
