[Nice] upnp support on windows

[Youness Alaoui]

I don't think anyone ever compiled libnice with upnp support for windows.
but if there's a port, then that would be good, last time I checked, the windows
port of libgupnp was non-functional and incomplete, so I never tried it.
Yes, gupnp-igd is fairly simple (and doesn't do anything low level, it just uses
libgupnp directly) so porting it would probably just require you to compile it
and no more.
UPnP is useful in some situations, When you look at the types of NATs
(http://en.wikipedia.org/wiki/Network_address_translation#Types_of_NAT) you will
see that STUN will not work with some types of NAT, and in the rare 5% or 10%
cases where the users have a symmetric NAT and connectivity can't be
established, then *if* they have upnp enabled in their router, then it solves
the issue entirely because the ports get opened directly without the need for
any sort of trick that may or may not work. It should lower the failure rates at
least for those who have symmetric NATs trying to connect to other symmetric NAT
users.

Congratulations on the release of the game! I hope it's being successful :)

Youness.
