The first commit is a duplicate for #81.

I linked this pull request to issue 81 beacause it was a upgrading feature, and it would be nice to upgrade to Ruby 1.9.3 and swaping jquery-rails to assets group.

What can I do to fix it? Create another pull request just with changes different to the rails version on the gemfile?

@p1nox #81 is also a pull request. The bigger problem here seems to be that the maintainers are not responsive.

Ok, I think that the solution here is to wait for maintainers decision, and sorry for the duplicated commit.
