Made changes for filtering and get/post request for config
I don't like this, lets keep the same model of endpoints being automatically wired up, and we handle all the web code. I would prefer we introduce a structure to the template manager so that at the top level there is a folder for GET and one for POST, if they post to a url, it has to have a matching template in the POST subdir.
