[ARMedslack] qemu-network-tun.sh modified script

[Davide]

If anyone else finds this handy this works with dhcp client on both host and guest and also gets rid of all rc.local requirements.
On the guest os you will need to config interface once system is up (static or via dhcp)
Needs fixing for static ip reconfiguration/rerouting on host system after bridge creation.

I apologize for my non standard indentation ...
