python api: add functionality to remove vertex color layers.

note: that this intentionally removes check to exit vpaint mode when a vertex color layer is removed,
	  since being in vertex-paint mode without a vertex color layer is supported.

also minor change to drawing camera limits while picking from previous commit.
