Merge branch 'develop'

This has been a long-running problem for days, but I've finally
implemented a correctly working hierarchy between the ClientData,
AccountData and CharacterData objects:

CharacterData -> AccountData -> ClientData

There doesn't seem to be any issues with it right now, touch wood.

-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.
+The most recent stable windows build can be found [here](https://dl.dropboxusercontent.com/u/46669050/Tortuga.rar).
 
-## Libraries
+Tortuga is an open source 2D multiplayer role playing game featuring permadeath (deletion of a character upon death). The emphasis of this game is on multiplayer cooperation, competition, exploration and customization. The game runs on customizable server software that can support up to 150 simultaneous players or more.
 
-* [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.
+This game is inspired by classic 2D RPGs, as well as more modern sandbox MMOs. This project is currently independently created and funded, with the goal of creating a game that will engage user's imagination and inspire a large modding community.
 
-## Instructions
+## External Dependencies
 
-* 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).
+* [SDL 1.2](http://www.libsdl.org/) - Simple DirectMedia Layer API
+* [SDL_net 1.2](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
+* [lua 5.2](http://www.lua.org/) - The lua programming language
