License should be added to the repo

[JudgeGroovyman]

If you add the MIT license to your repo like this repo did then it will be improve discoverability by making this repo searchable by license and also be instantly obvious when potential users are browsing it. I realize that the license is listed at the bottom of the readme file and thats certainly a positive step. I think you just have to add a license text file in the main folder of the repo (next to the readme.md).

P.S. I'm about to use Uween and am looking forward to it. It looks great!

P.P.S. Probably worth updating the copyright at the bottom of the readme file while you are at it.
