Noah Petherbridge 3892087932 Doodads: Use Key and Working Warp Doors
* The "Use Key" (Q or Spacebar) now activates the Warp Door instead of a
  collision event doing so.
* Warp Doors are now functional: the player opens a door, disappears,
  the door closes; player is teleported to the linked door which opens,
  appears the player and closes.
* If the player exits thru a Blue or Orange door which is disabled
  (dotted outline), the door still opens and drops the player off but
  returns to a Disabled state, acting as a one-way door.
* Clean up several debug log lines from Doodle and doodad scripts.
