Heard that multi-bone selection would be better used for painting multiple bones; took out select lock.

Added a basic multiple bone group paint feature "Multi-Paint" and its corresponding checkbox next to "Auto Normalize," but I need to access the ToolSettings for it in armature to make bone selection function/draw correctly

When you multi-paint, it paints on selected bones while keeping the weight ratios on a vertex of the selected groups the same. You can't currently multi-paint on a vertex with a locked deform group.
