Add sinatra skeleton and set up basic database with some
validations.
Can't get the validation to set a maximum of two players
on the game.
Make first integration with Sinatra.
It's a little messy, some active record validations don't work
and needs a lot of polish, we also realized that we need to
know about Ajax to make the backend and the frontend
communicate.
