Require Grape 0.16.1 and fix route_xxx deprecations.

[dblock]

This isn't ready to merge. there're issues with route_params and route_hidden.

Closes #364.

[dblock]

For now I am monkey-patching the deprecation to avoid too many warnings being spewed.

module Grape
  class Router
    class Route
      private

      # TODO: remove when https://github.com/ruby-grape/grape-swagger/pull/368 and https://github.com/newrelic/rpm/pull/235 are finished
      def warn_route_methods(name, location, expected = nil)
      end
    end
  end
end

[LeFnord]

please respect also route.success → see: describing-methods

[dblock]

that needs a spec I suspect, wasn't caught

[LeFnord]

success is the new entity and failures the new http_codes, think a small spec to proof both new work in the same way as the old one should be enough

[dblock]

Actually no need, these were declared as DSL sugar on top of the entity and http_codes implementation in https://github.com/ruby-grape/grape/blob/1097eb192a8601234b5465c23b1ab09101048792/lib/grape/dsl/desc.rb#L90, so they work today out of the box.

[dblock]

@LeFnord once this is all fixed here, should I be merging it onto master or swagger-1.2?

[LeFnord]

@dblock please merge to swagger-1.2, so we could release the actual master as 0.10.5, and this work for 0.11.0

[dblock]

Closing in favor of #375.
