Title: Upgrade to RSpec3

RSpec 3.x introduces a `spec/rails_helper.rb` file
which contains all dependencies necessary to run specs that need Rails.

* Move Rails-specific things to rails_helper.rb.
* Require spec_helper.rb from rails_helper.rb.
* We do not need to require `spec_helper` manually.
It is required for us in `.rspec`:
--color
--require spec_helper
