Tested SendAll(), end of this prototype

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.

+Tortuga is a 3/4 top down multiplayer RPG set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer competition, exploration in an open world, and solo adventuring. The game runs on a Minecraft like server system with a goal of about 50-100 players on a single server. The player characters are tied to the server where they are created, and are susceptible to permadeath: deletion of a character upon death. The servers are designed to allow a large amount of modification by the hosts.
+
+## Libraries
+
+* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
+* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension; modified source included under libs/SDL_net
+* [Codebase](https://github.com/Ratstail91/Codebase) - files included locally; modifications will be included upstream further into this project.
+
+## Instructions
+
+* This project uses C++11, which is available via GNU (or MinGW) 4.7, or Visual Studio 2012. Personally, I'm using MinGW 4.7.2.
+* You need to build the library in the common/ directroy before any others.
+* I'm trying to keep this as IDE agnostic as possible, so if you use an IDE, please add it's files to .gitignore.
+* You can read more details on the GitHub wiki [here](https://github.com/Ratstail91/Tortuga/wiki).
