additional optimizations and permission handling
Optimizations for handling XMPP data and commands Basic permission handling - Add fuid users to bot - Ozmo has ACLs and an "owner", if bot comes from eco to bumper the fuid_user won't have permissions - Bumper will add the fuid_ user to bot ACLs and grant full - This can be used later when bumper adds proper auth to allow/block users
