Some characters have a preferred set of initial values for morph targets, however, these morphs should not influence those created by pose asset processing. We should set the relative key for all pose asset created shape keys to a custom basis created from mix if initial morphs exist.
This PR also removes the initially added 'Basis' shape key during pose asset processing if no other shape keys were created (i.e. sometimes for Body or FaceAcc character parts).
