have the frontend app disable/enable GA tracking based on the users choice on the `anon-tracking-enabled` setting.

move the settings stuff created by Cam into the superadmin section where it makes more sense.  purge the old superadmin pages which weren't doing anything yet.

move /frontend_client -> /resources/frontend_client to make sure the static resources are bundled in our jar files.
small updates to main routes.clj file to make static asset serving from "resources" instead of "files", which allows for serving out of jars.
