Removed Control.Update, moved all update code to Control.FrameUpdate. UI controls have no business running code inside simulation Ticks. Because of how the update loop is ordered, this will actually make the UI elements more responsive to simulation changes.

Fixed multiple bugs in the action UI where the Control.Update method was calling the base Control.FrameUpdate.
