Title: Cache public/assets if turbo-sprockets-rails3 is present in Gemfile.lock

Finally, here's a pull request that just provides support for the [turbo-sprockets-rails3](https://github.com/ndbroadbent/turbo-sprockets-rails3) gem for Rails 3 apps.

It loads any assets from the cache before compiling, runs the `assets:clean_expired` task to remove unused assets, and then caches assets at the end.
