- implemented GojaraAdminManager & GojaraAdminProcessor, send admincommands to admin configured Spectrum & process returning Information
- create adminuser gojaraadmin, remove it when plugin is destroyed
- fixed not showing all open sessions when plugin restarts / loads through querying spectrum2 for online_users
- implemented unregistering registrations on spectrum side with admincommand unregister <barejid>
- check if transport is active before trying to remove the registration, maybe do specific new command for just deleting info on our side
