GSOC 2013 paint

Yep, at last it's here!

There are a few minor issues remaining but development can go on in
master after discussion at blender institute.

For full list of features see:

Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.
