Codebase update: Added transparency control to Image

I just _had_ to get rid of that horrible libs/ directory. Now most of the
graphical stuff is in client/, but I'll create more subdirectories so that
they're not getting in the way.

-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.
+_This project is currently in it's early prototype stage. You can see other versions in various branches or tagged as prototype-X._
 
-## Libraries
+Tortuga is a 2D multiplayer role playing game set in a large archipelago occupied by warring pirate clans. The emphasis of this game is on multiplayer cooperation, competition, and server customization. The game runs on highly customizable server software that can support up to 150 simultaneous players or more. The player characters are tied to the server where they are created and are susceptible to permadeath: deletion of a character upon death.
+
+## Dependencies
 
 * [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.
+* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
 
 ## 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).
