[Bf-committers] Blender 2.68a release AHOY!

[Campbell Barton]

Hi, regretfully there were a few bad regressions in 2.68, so I've
merged fixes into a bugfix tag and committed splash & version bump.

Information for platform maintainers:
tag: blender-2.68a-release
tag revision: 58536
addons revision: 4630
locale revision: 2100

note that addons and locale are same revisions as for 2.68.
