Added bower.json for inclusion into the bower system

Hi there,
  I was wondering if you wouldn't mind looking this over and pulling it, if you see fit. I'm wanting to use your plugin with bower and this would make it easier for me (and anyone else who uses bower) to automatically inject your js into the web project I'm using it with.

Also it would be good to have if you wanted to include you project into the bower components registry.

Hope it all looks correct.
Thanks,
Cody
