[Bf-taskforce25] Wrapping pose channel vs. bone flags and other stuff

[Roland Hess]

Joshua -- saw your note in the armature/bone rna about whether to wrap 
the bone or pose channel version of that data. My vote would be to keep 
it in bone, and for the most part leave pose channel unwrapped. 
Re-looking at the two, there isn't as much overlap as I remember.

I'd suggest: wrap for read-write (when appropriate) in Bone, and also 
wrap in Pose channel but read only, and a note in the doc string that 
it's a bone-level flag.
