use armature active bone as a pointer rather then a flag for each bone that needs looking up.

- rna vars arm.bones.active & rna.edit_bones.active
- needed special undo support.
- readfile.c loads.
- duplicate and copy_armature support.
- keep the draw flag, renamed to BONE_DRAW_ACTIVE, only use for openGL drawing.

Note: it may be better to allow active/unselected as with objects.
