Just have all xpdev apps link with winsock import library

Gave up on trying to isolate socket-enabled (networked) and non-socket apps. Just link everything that uses xpdev (which is everything, I think) with the WinSock import library. Fixes the current master branch build issue on Windows. I'll get around to removing the old NO_SOCKET_SUPPORT macro eventually.
