Adds slot machines to the game.

What it says on the tin.
It works with coins and shit.

emagging it is top lyl and shoots the coins at you.

Probabilities and values are currently completely arbitrary, feel free to suggest changes.

This does not place them on the map.
Add the coin as an argument. The code is currently hard to read and putting all of these complicated bits of code into their procs will make it easier when you can just read their proc names to get a sense of what it does.
