* 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.
