Muuuuuuch things.
- It can now uses a different database than the panel. It does als use the Panel's one, but only when it needs things from there.
- Now uses Mongo to determine which Daemon+Server is meant to get the commands, based on VirtualDaemon+VirtualServer.
- Renamed MultiCLient to MultiPanel totally.
- Made PanelDB, to query a panel specific database. Maybe gonna keep this connection up later. (MultiPanelPool? PanelDBPool?)
