Rename project

[jhoffner]

Maybe call the project codewars-local (or something better, thats all I can think of right now). That way the project is more descriptive, and since codewars is releasing a number of open-source projects, it will help to keep things organized.

@jhoffner I'm not opposed to changing the name to codewars-cli and giving you guys codewars for a lib or something. Also, both you and @nathandoctor have full access to this repo, so feel free to change it. The only thing I ask is that you make those changes on a branch and merge them in through a PR (so we can discuss).
