Maya Better UV Packer

Respects unselected UV shells and treats them as obstacle during packing so as to pack around them instead of overlapping on top of them.

Why is this required: Because Maya will not respect any UV you might have packed by hand during automatic layout, so it will always overlap on top of what you have. That's not too great when packing multiple assets into one, specially since you might have packed some before by hand.
