2.50: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r18677:19317

Notes:
* Sequence transform strip uses G.scene global, this is commented
  out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
  2.5 got merged, but no new files were added. Calls to these files
  are commented out with "XXX etch-a-ton". editarmature.c and
  transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
  (player still fails to link).
