Keyframe mirroring on a puppet

• It basically mirrors all keyframes affecting the puppet according to the mirror the puppet already obeys by. So if one keyframe moves the right arm up, you press this toggle and the left arm gets moved up instead.This could be a toggle in the puppet bone menu and be powered with a wire/keyframe.

Use case:

A puppet has a pose where it's aiming a rifle in a third person shooter and is also keyframed to move up and down. With the press of a button you can then make a shoulder swap mechanic without needing to do a second pose and it's up/down positions.
