Networkpatch for Grand Prix Legends, Nascar 2002 and maybe other Papyrus games

[Christoph Frick]

hi!

i asked in the devel list two times for help about this issue - but no one was
able to push me in the right direction. Maybe submitting it as patch cause
some reactions :)

The patch make the games Grand Prix Legends and Nascar 2002 work - and
Neverwinter Nights still works with it.

CU!

ChangeLog:

	* dlls/winsock/socket.c: 
	Christoph Frick <frick at sc-networks.de>
	Force (WS_)SO_REUSEADDR before binding to a socket; ignore
	(WS_)SO_DONTROUTE; Network games in Grand Prix Legends and Nascar 2002
	are possible now.
