Split DBUS_SESSION_BUS_DEFAULT_ADDRESS into listen, connect addresses and set better defaults

Browse source 
On Unix, the connect address should basically always be "autolaunch:"
but the listen address has to be something you can listen on.

On Windows, you can listen on "autolaunch:" or
"autolaunch:scope=*install-path", for instance, and the dbus-daemon is
involved in the auto-launching process.
