I fucking hate collisions

Conflicts:
	server/server_logic.cpp

Finally merging the changes to develop. This is only the ConfigUtility
skipping missing files, and something with the Timer class, that I'll need
to test the collisions.

-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.
+## Outline
 
-## Libraries
+Tortuga is a 2D multiplayer JRPG featuring permadeath, with an emphasis on multiplayer cooperation, exploration and customization. The game runs on customizable public and private servers.
 
-* [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 (Final Fantasy, The Legend of Zelda), as well as more modern sandboxes amd MMOs (Minecraft, EVE Online). This project is currently independently created and funded, with the goal of creating a game that will engage the players and inspire a large community.
 
-## Instructions
+## Releases
 
-* 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).
+The most recent stable build for Windows can be found [here](https://dl.dropboxusercontent.com/u/46669050/Tortuga.rar).

+This is the README for Tortuga's demo build. The source code is available at:
+
+   https://github.com/Ratstail91/Tortuga
+
+The current build may have bugs, missing features, bugs masquerading as
+features, etc. You can report a bug/feature here:
+
+   https://github.com/Ratstail91/Tortuga/issues
+
+Please note that this game requires a functioning server to operate correctly.
+Both a game server and game client are included in this package.
+
+-------------------------
+Instructions For Setup
+-------------------------
+
+1. To create a server, simply run server.exe.
+2. To join that server, run client.exe with config settings not already in use.
+    (Note: This process will be streamlined later).
+3. To change the config settings, open rsc/config.cfg
+4. These settings must be unique for each player:
+
+* client.username
+* client.handle
+
+5. There are currently two options for 'client.avatar':
+
+* client.avatar = elliot2.bmp #male
+* client.avatar = coa2.bmp    #female
+
+6. When you've correctly set these values (good luck), select 'Start' from the
+    main menu; this displays the list of available servers.
+7. Select the name of your server (default is 'local') and select 'Join'.
+8. Welcome to Tortuga, enjoy your stay.
