Moved UI gem dependencies from the main repo

The jquery-rjs is included from our fork on GitHub and there is no
support for unreleased gems in a gemspec. I also tried to move it
to the UI Gemfile, without any success. So until we don't push it
to Rubygems.org, it needs to stay in the main repo's Gemfile.
