Added Abandoned Crates!

Abandoned Crates are random crates that Miners may come across while digging. They are locked with a deca-code locking system, and you have 3 tries to guess the code before it goes off. You can use a multi-tool to tell you if your last guess was too high or too low, allowing you to play a hot or cold game with it to get the loot inside. It's possible for anything to be in there, so who knows what might come out! See: Abandoned crates from Goonstation 13.

The base code was the old ISaidNo release to oldBS12. I fixed it up, standardized it, and made it work on TG.
