[BUG] Fading door glitch

[maddawg]

You can't change the key for a fading door, it always stays the same.

Ex: You make a door the up button, then accidentally make another door that button, but meant to make it the down button. So you take the fading off the door, and re-fade it with the down button set instead. However, it still opens with the up button instead of the down.

(I can't remember if the down and up button would BOTH open it, or just the up button.)

Fixed.
