Added 2 new commands to my slack project!

I added a rock paper scissors command: /blaze-rps
The user chooses an option from a list: rock, paper or scissors. Then, the bot chooses a random one. There is a hardcoded list in the code for saying what beats what.
… yep

Also added “flip a coin” which basically just picks a random option between heads and tails and tells the user the answer
