Add bower.json support

Created bower.json file for installing package
via bower.

Fixes #13
FYI @peterblazejewicz the `bower.json` *file* isn't required to install a package from bower. If one wanted, they could install this repo as a dependency just using it's git URL. The benefit of having bower.json is ignoring files (like tests, source code [coffeescript], etc.) and tagging releases. 

So to answer your question, no the `version` is not required, but just as the docs say... you *should* have it.
