The before/after filters don't work when they are inserted after the target route in controller.

Edge::App.controllers :test do
  get(:index){ @foo }
  before(:index){ @foo = "Hello World" }
end

get "/test/" #=> Expected: "Hello World", Actual: ""

To indicate the problem this should be 2 lines lower. Then without the patch it fails.

OK, thanks for the reviewing. I'll change order of commits, and add a test about this problem.

This looks good to me.
