Gemfile works with JRuby 1.5.1, tests run

The :mongoid group does not work in JRuby so the group
is only defined for the platform: 'ruby'.

In addition installing ruby-debug in JRuby is a manual process so
only include the dependency if we are using the platform: 'ruby'

Here are the steps necessary to run the devise tests in JRuby
using rvm:

  rvm install jruby
  rvm use jruby@devise --create
  gem install bundler --pre
  gem install jeweler
  bundle install
  rake test
