Add First Gambling Function

Since jiaozi supply is infinite, but the increase % is decreasing, then any fixed % burn mechanism will reach equilibrium with the issuance at some point in the future.

Ghost Carapace proposed a gambling dapp that would allow people to donate tokens to a pot. When the pot reaches a certain amount, the last donated address recieves 80% of the pot, 10% is burned, and 10% is used to start a new pot. If nobody donates to the new pot for a day, the last address to donate to the pot can claim it.

This creates a continuous 10% burn EVERY SINGLE POT CYCLE.

Do you think this is a good idea?
