IdleAnim

IdleAnim is a strange and specific animation case that is used on service depots in RA2 (in TS this tag didnt exist). Service depots used 3 special anims to play certain repairing animations and when no repairing animation was in progress it used its IdleAnim as a way to avoid layering issues. Then in YR, IdleAnim logic was expanded to handle two more cases; the first case is on the yuri conyard- the idle anim works in tandem with the production anim in order to render the conyard's crane correctly. The second case is the soviet industrial plant, which for completely unknown reasons, seems to have been hardcoded to play its idle animation like an active anim.
