- netcode cleanup.

Browse source 
This moves all parts in the Duke/Redneck modules that access ENet into net.cpp/network.cpp and changes global ENet structs to use C++ notation instead of typedefs so that anonymous definitions for them can be added where needed.
These changes are done to avoid including enet.h globally which is a major issue because this file does not work without including windows.h, making it extremely dirty.
