Rails 3.1 Support

[ghost]

I tweaked the script to work with rails 3.1 by making the following changes:

changed instances of RAILS_ROOT to Rails.root
and save_path now equals "#{Rails.root}/app/assets/javascripts/#{filename}" for the new assets feature

If you make a pull request I can merge the changes into the master branch, or if you'd like, I can simply make the changes myself. Thanks for the heads up!

I should have mentioned, I'm more of a hobbyist at this point and don't really know how to use Git so the latter option would probably be best :)

Sounds good. I'll add the changes once I'm home from Railsconf, and close the issue when that happens. Thanks again for your help and input.
