Bower Support

Adds support for loading through [Bower](http://bower.io). It's under the name `socialite-js`, because [an outdated fork of this repository](https://github.com/igoldny/Socialite) has already claimed `socialite` :(

If this pull request is merged, to actually register it with Bower you'll need to run the following command:

~~~sh
$ bower register socialite-js git://github.com/tmort/Socialite.git
~~~
