Create bower.json

Adding this project to bower would allow many more people to use it(it is pretty great).

This pull request adds a functional bower.json, but to distribute this package to bower read [the bower website](http://bower.io/#registering-packages).

Also will want to use [semver](http://semver.org/), doing something like 2.3.0, 2.3.1 instead of 2.3.
