* Change the object used in routing constraints to be an instance of

  ActionDispatch::Request rather than Rack::Request.

* Changed ActionDispatch::Request#method to return a String, to be
  compatible with the Rack::Request superclass.

* Changed ActionDispatch::Request#method to return the original
  method in the case of methodoverride and #request_method not to,
  to be compatible with Rack::Request
