MethodHandler added

Hey Alexander
I saw a post where you've mentioned that you'd like to take over this project as the original repository is pretty much dead. I forked your repository and will send the pull requests to you. Let me know if that's okay!

This pull request is about the methodhandler.go example which doesn't work anymore. More about this can be found in this issue https://github.com/hoisie/web/issues/90
