[Bf-committers] Collecting fixes for "2.66a" release.

[Campbell Barton]

Hi I went over commits since release and make a suggested list of
changes to be included in 2.66a.

There are some areas I'm unsure of:
* Mougri's BGE animation fixes (mixed in a bit with refactoring).
* Aligorith made some animation fixes after fairly large commits to
animation code.
* Sergof's Bullet/Physics are mixed with features and fixes. need
feedback which are safe for release.
* Cessen made changes/fixes to Rigify.
