Ton Roosendaal 59672145a9 Cleanup & goodies for rigging geeks! :) 
- PoseMode: Wkey menu, "Flip Left/Right Names". On selected bones, it flips
  the L/R tags in names, and calls the proper code to rename everything
  that's related (constraint targets, bone-childs, etc).
- PoseMode: Shift+S snapmenu: snap cursor to selected now works
- Outliner: select bones now correctly sets 'active' flag for bones,
  updating the UI as well.
  Also made sure you cannot select hidden bones in outliner.
- 3DWindow: in PoseMode/EditMode draws name of active Bone too (with user
  option "Draw active object name" set.
- Added the new Armature/PoseMode options in View3D pulldowns.

Cleanup:

- moved Pose code from editaction.c to poseobject.c
- removed BSE_editaction.h and BSE_editaction_types.h, moved contents of
  it to BIF_editaction.h. One include per C file should be fine. :)
  I know the src/ structure would require more elaborated includes, but
  we don't have that now...

The buffer and ListBase have the same relative order, which makes the selection

and object pair, if not, just move to the next object,
keeping the same color until we have a hit.
The buffer order is defined by OGL standard, hopefully no stupid GFX card
