Subject: [PATCH] add clickable dest signs

Dest signs are denoted with [DEST] or [DESTINATION] on the first line. A dest sign can have one dest per remain line on the sign. Players can punch the sign to cycle through the available dests. Destinations prefixed with "/dest " will have the prefixed removed automatically.
