More armature goodies;

The B-Bones!
(where the B can be read as 'block' or 'bezier' or 'b-spline')

- set option on/off in edit buttons, armature panel
- scaling of B-bones only works in editmode, use ALT+S to make bones fatter
  or thinner. Also works for constrainted transform
- In pose mode, you now have a buttons panel with per-bone settings too
  Here you can find the "segments" button, which allows bones to
  interpolate between previous/next bones, including roll.
- Buttons to control interpolation ("In" and "Out" are disabled, doesn't
  work satisfying yet

NOTE: this doesn't give deform yet! Main purpose for now is to test if this
drawing method serves to animate/pose armatures well.
Still need to review proper interpolation methods... maybe bezier is too
limited.
