Chain rotations for objects and pose bones (for teamto)

This commit adds an exception for rotations (standard rotation and tracball) to still work on children of transformed objects and bones in an expected fashion. That is, you can select a chain of finger bones and rotate to flex them all at once.

Notes:
[1] This could be expended to other transformations if needed.
[2] Center of transformation is determined using the same principle as hinge bones (transformed children aren't taken into account)
