#7 Bowerification

Hi Rhys,

this is a pull request for the request #7.

I have added a configuration file for bower and replaced the included dependencies (backbone.js etc.) by the ones resolved by bower.

Unfortunately I didn't have enough time to fix the testacular tests yet, sorry. If you like I will have a look and probably update the test suite to a current version of karma.

To submit the package to bower, run the following line in the project's directory:

    bower register backbone.advice https://github.com/rhysbrettbowen/Backbone.Advice.git

Cheers,
- Julian
