lhnet fixes - now calls WSAStartup during LHNET_Init and WSAShutdown during LHNET_Shutdown, so gethostbyname will work on windows without any sockets open (as long as LHNET_Init has been called of course), fixed a few things that were breaking compilation with -DSTANDALONETEST and added a new simpler and more useful standalone test program which is now used by default (edit the #if if you want the old one instead)
