Remove the teleporter malfunction

[Twoflower]

As it is now, the teleporter (old one, not telesci) has a pretty decent chance of teleporting you into space instead of your destination. This makes the teleporter a lot less useful than it could be, because who wants to use anything that has a chance of randomly ending your round in an unfun way? Removing the malfunction chance would let it be used more as a way for people to break into things and as a cool escape method for heads.
