Merge branch 'develop'; major refactoring complete (read more)

Streamlined the build process, including:
* Restructured the common directory
* Moved the client's scenes up one level
* Removed the unused DEBUG flag, added the GRAPHICS flag
* Moved the server's data structures to the common/gameplay directory
* Data structures are now shared by the client and server

Other changes include:
* Created the StatisticData structure
* Removed the server's static variables
* Some progress on basic combat system framework
* CharacterData now has methods (derived from the delete PlayerCharacter)
* Client-side tables are now shared between the scenes
* Refactored UDPNetworkUtility, tying it to SerialPacket
* Added new structures to SerialPacket, and serialization
* Renamed and rearranged the SQL tables
* Solved a few other TODO tags
* Updated the license headers

-_This project is currently in it's early prototype stage. You can see other versions in various branches or tagged as prototype-X._
+The most recent stable build for Windows can be found [here](https://dl.dropboxusercontent.com/u/46669050/Tortuga.rar).
 
-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.
+Tortuga is a 2D multiplayer JRPG featuring permadeath (deletion of a character upon death). The emphasis of this game is on multiplayer cooperation, exploration and customization. The game runs on customizable server software that can support up to 150 simultaneous players or more.
 
-## Dependencies
+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.
 
-* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
-* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension
+## Documentation
 
-## Instructions
+Tortuga's full documentation can be found in a separate branch, see [Tortuga/docs](https://github.com/Ratstail91/Tortuga/tree/docs).  
+For Tortuga's primary documentation, please read the [Tortuga Game Design Document](https://github.com/Ratstail91/Tortuga/blob/docs/Tortuga%20Game%20Design%20Document.docx?raw=true).  
 
-* 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).
