Package up for the rails asset pipeline.

We're using this for some of our apps at work and wanted it packaged up as a ruby gem.
I'm not sure if you want to add another package format to your project but thought it might be interesting.

This is wrong. It's also getting harder to keep all the various versions in-sync. Perhaps it's time to add a task to the Makefile to bump the version in this file, `bower.json`, and `package.json`.
