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.

+_This project is currently in it's early prototype stage. You can see other versions in various branches or tagged as prototype-X._
+
+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
+
+## 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.
+* 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 Tortuga wiki [here](https://github.com/Ratstail91/Tortuga/wiki).
