Fix more windows.h/winsock.h/winsock2.h issues

We want to use winsock2.h rather than winsock.h. This was mostly enforced
from the global_defines.h file, but I wanted to make it consistent.

Most of these includes can be removed since they're included via
global_defines.h, but someone on windows should clean that up

zone/client_process.cpp
