Enhancements:

* Add support for PATCH to route specs created via scaffold. (Igor Zubkov, #1336)
* Improve controller and routing spec calls to `routes` by using `yield`
  instead of `call`. (Anton Davydov, #1308)
* Add support for `ActiveJob` specs as standard `RSpec::Rails::RailsExampleGoup`s
  via both `:type => :job` and inferring type from spec directory `spec/jobs`.

* Include `RSpec::Rails::FixtureSupport` into example groups using metadata
  `:use_fixtures => true`. (Aaron Kromer, #1372)
* Include `rspec:request` generator for generating request specs; this is an
  alias of `rspec:integration` (Aaron Kromer, #1378)
* Update `rails_helper` generator with a default check to abort the spec run
  when the Rails environment is production. (Aaron Kromer, #1383)
