Subject: Do not show floor set label option to non-owners

Change elevator formspec to hide set label option of elevators which are protected from players who do not own them. This avoids confusing players. Unprotected elevators are properly unaffected and forms with culled label option are shrunk in height by 1.6 units respectively.
