add_sign
Large messy chunk of code. You HAVE to get this right or it
just won't work.
add_sign(string long, string read_mess, string short, string name);
"long" is what you see when you "look sign"
"read_mess" is what you get when you "read sign"
"short" appears in the room inventory
"sname" is optional, defaults to "sign"
add_sign("A large battered wooden sign.",
