Major - Morgan additional rigging jumper extract deltas

Before moving onto the animating process I wanted to make some refinements to Morgans rig. Throughout the start of the animation Morgan is mainly sitting so naturally folds will form on her jumper when she is sitting, however the rig cannot properly communicate this. I've had to use Extract delta's to create meshes to communicate these shapes properly. However since I cannot predict how Morgan will sitting and moving around during the animation stage I will also have to create additional shapes along the way.
