Created empty TCPNetworkManager; needs work, I don't even like the name
Worked out the basic server layout
Imported ConfigUtility, updating it for this project
What am I doing wrong?
So that's what I was doing wrong
Changed my mind about networking system structure
Updated this project to the new standard, see details.

After a significant modification to the Codebase library, I imported a lot
of the Codebase updates back to this porject. Some files that exist in
Codebase still carry the zlib license header; these files are still under
the zlib license.

Following a significant struggle with SDL_net, I've decided to ditch that
library and write my own version. It currently only supports TCP
networking, and only works on windows platforms,  but it is sufficient at
this time.
