Bower packaging

[samuraisam]

Wanted to use this in my app without having to manually manage the dependency, so I've defined a bower package and cleaned up a few other things along the way:

• removed vendor files (now uses bower to manage dependencies)
• updated dependency paths on test runner
• added built version to the to repo for easy bower installability

Hopefully someone else finds this useful!

@samuraisam great! Thanks for this PR.

I downloaded your branch locally and ran the tests. They seem to be failing:

Do you mind checking this? I'd love to merge this PR once all tests are green (we can't use TravisCI because PhantomJS has no IndexedDB support).

@samuraisam hey, I fixed those tests locally. Check #6. I'm closing this for now.

@krainboltgreene it would appear someone else has registered a package of the same name on bower (which is a first-come, first-serve registry). You can use this repository's URL as the package (see bower docs for more info).
