- bone.basename now only gets the name before the first '.', since names like finger.01.L are common

- updated delta not to remove a bone
- spine and neck rigs interpolation bones are now axis aligned to the control bone
- palm tag is expected on the pointer finger rather then the wrist
- operate on bone children first working up the chain (not essential but more pradictable)
