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.
