mod_http_oauth2: Rescope oauth client config into users' storage This produces client_id of the form owner@host/random and prevents clients from being deleted by registering an account with the same name and then deleting the account, as well as having the client automatically be deleted when the owner account is removed. On one hand, this leaks the bare JID of the creator to users. On the other hand, it makes it obvious who made the oauth application. This module is experimental and only for developers, so this can be changed if a better method comes up.
