original bone names cant be changed anymore but this means the bones can be re-parented without confusing scripts that run after the rig is modified.
support for defining a bone to have multiple types and automatically blending between 2 generated rigs
new bone properties
- bone.basename (name without the extension), "Some.Bone.001" --> "Some.Bone"
- bone.children_recursive_basename, gives a chain of children that have the same basename
