Moved dependencies from the Gemfile to the gemspec

* The Gemfile now contains just the source and a single `gemspec` declaration
* See http://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gemfile/

* Also had to break out the modules under integrations/rspec into their nested equivalents (load order?)
