Added Bower support

Created a bower.json manifest to allow registration with the Bower front-end package management system (http://bower.io/).

I took a couple of liberties with some of the settings, feel free to change accordingly. Not sure on whether  there is a need to add some items to the 'ignore' section of the file.

The bower homepage explains how to register a package:

http://bower.io/#registering-packages

Let me know if you need any other information.
