Christoph Oelckers 6c5d9c3507 - moved the net init code out of the game frontends to avoid having to call atexit for their deinit function.
When doing this during startup it can be done by regular cleanup measures.
This also moves two larger chunks of networking code out of game.cpp.

Nevertheless, the fact that enet is a very dirty library which directly depends on Windows types is a big problem because it bleeds Windows definitions everywhere thanks to poor abstraction in all relevant layers.
