Allow KogeCoins to be used for games at PolyRoll

This proposal from the team seeks to provide a new use case for KogeCoin: allowing it to be used for games at PolyRoll (e.g. Coin flip, dice roll, roulette).

If passed, a portion of KogeCoins in the marketing wallet (~$20k) will be invested to a game contract designed by PolyRoll to fund potential prizes. The contract will be owned by the KogeCoin team, and the marketing wallet allocation can be withdrawn at any time should there not be a lot of interest in the games.

Because the games have a casino edge, this is in expectation a net positive investment. That is, the marketing wallet allocation is not meant to be a cost, but rather revenue-generating. Any profits will remain in the marketing wallet where it can continue to be governed by the community.

PolyRoll will take an undisclosed cut of each play to compensate for their operating costs, an amount which we found to be reasonable.

Here are the pros and cons:

Pros: good for marketing/exposure, new use case for token, possible profits for the marketing wallet

Cons: tying KogeCoin with casino games may not be "family friendly" in terms of image
