WIP - Adding support for RSpec 3
Updating code to work with RSpec 3
Finished adding support for RSpec3.
Making RSpec::Mocks::ExampleMethods available in set_up and tear_down,
so the allow method is available without configuration.
Releasing version 1.2.1.rc1
Added missing Gemfile.lock from previous commit
Merge branch 'rspec_3'
Ensuring the pact RSpec formatter works for both rspec 2 and rspec 3
