Adds Cecil (#119)

* Add Cecil for mechanics Used to predetermine the outcome of games according to a probability function, which is stored as a skew. Each game made using cecil is intended to have its own skew (or maybe multiple skews for different difficulties) Will eventually be used for planes 2 * Add CecilCommand for gambling functionality Skip all the fancy casino visuals and let Cecil take the wheel Customizeable difficulty !cecil <bet> <optional difficulty, default 1> <optional max win> https://i.ddos.lgbt/raw/CecilHelper.html * Validate max win value in CecilCommand Added validation to ensure max win is greater than 1. * Adjust slot symbol probabilities and random range 9208000 | Payout: 0 | RTP: 97.84% | Feach Chance: 0.78% | Hit Rate: 34.03% | Win Rate: 15.14% | Biggest Win: 14100.0x | Avg Win: 6.01x | Median Hit: 0.6x got some complaint about slots so figured I'd change it up a bit
