From soc-2014-shapekey branch, with minor edits by mont29 (Bastien Montagne).

Fix sequencer duplicate with only handle selected

Fix T42264: Negative scale & clipped-select fails

Thanks to mont29 for finding the cause.

Fix sequencer clipboard with meta's containing ID references

Fix T42189

Own mistake - not copying enough data.

Fix T42311, too many paint slots added.

Don't allow the add paint slot operator to redo. Also guard better against
excessive slot addition

Fix T42313: Ruler always measures 0.0

Passing 'ar' to snapObjectsRayEx would apply a ray-offset.

Fix T42304: blender 2.72a 3D view object selected color wrong in 2.4x theme.

I would not have endured such a critical and monstruous bug one more femtosecond!

And even worse - active color was awfully wrong too! Shocking!

Fix issue reported by Sebastian Koenig on irc, Clone brush would paint
trash with float images.

Issue is uninitialized alpha in the clone brush + a clamping issue for
float images. There's still some 'swimming' and brightness issue here
but I have to do work for the weekly, will investigate further later.

More fixes:

* Fill brush did not do proper srgb conversion for byte images (reported
by Sebastian Koenig, thanks!)
* Color sampling for palettes did not refresh the toolbar.

OSX/PLAYER/cmake: fix player install python bundling, overlloked player has its own PLAYER_TARGETDIR_VER

Fix for pose bones not restoring selection index properly
