Separate Rails additions to bbq-rails #41
Description
Things like:
- https://github.com/drugpl/bbq/blob/master/lib/bbq/rails/routes.rb
- https://github.com/drugpl/bbq/blob/master/lib/bbq/railtie.rb
are useful but totally not essential to core. This would help to resolve dependency problems as well and move responsibility to test compatibility with Rails to that gem.
