Make filetype infer opt-in

 * Extracts the `mock_model` and `stub_model` methods to the
   `rspec-activemodel-mocks` gem. (Thomas Holmes)
+* Spec types are no longer inferred by location, they instead need to be
+  explicitly tagged. The old behaviour is enabled by
+  `config.infer_spec_type_from_file_location!`, which is still supplied
+  in the default generated `spec_helper.rb`. (Xavier Shay)
