Added a new vending machine which vends mostly everything that randomly spawned in the theater and a few extras.
Also recolored an unused vending machine to use for this machine.
Changed the sprites slightly, mask light flickers and the deny light flashing is more noticeable.
Changed the vend_reply to one phrase because it said both and I don't know why.
