Update obsoletes in BoneSimulator, remove PhysicsGroup enum

Lets go ahead and update the obsoletes for 7.3. I also removed the
enum describing the PhysicsGroup because:
1. I don't really know if it can be truly exhaustive, or if they
reuse the same rows for different purposes.
2. You should really be looking at the Excel sheet instead, because
it's literally an index into that.

Whoever was using the enum can copy that into their project
instead and deal with figuring out which rows are which.
