Blender Git Loki

Three little feats;

- Vpaint and Wpaint now use our own custom cursor, this was a very old
plan anyway. It uses the 'knife' now, we need a good brush icon for it!
- On scaling bones in editmode, the deform distance info gets scaled now
too when no "Envelope" draw mode was set.
- Disabled front buffer drawing of objects with CTRL+select in Edit Mode.
Uses a regular redraw now (like for select in Object Mode btw)
