Wrote a simple passive timer for debugging

After a few days of work, I'm committing what i've done so far. Mostly
I've cherry picked the best parts of the multiplayer branch's modules, and
adapted them for use here. I've written a few new components, and I've
learnt a few things along the way. I may continue with this branch for a
while, before moving the changes into the main branch. Alternatively, it
might turn out that this single player version is more fun. We'll see.

I've swapped the config system for a pure lua version instead. This is
actually fairly flexible. I've also changed the map system and it's API a
great deal. The tile sheet can be loaded from lua, and the save directory
isn't hard coded anymore. I think this would be a good testbed for a lot
of different systems, including the collision system, however the current
system (using vectors) is inadequate. I'll have to dig up the old BBox,
possilby.

This branch will piggy back on the main repo for a while.

-_This project is currently in it's early prototype stage. You can see other versions in various branches, tagged as prototype-X._
-
-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.
-
-## Libraries
-
-* [SDL](http://www.libsdl.org/) - Simple DirectMedia Layer API
-* [SDL_net](http://www.libsdl.org/projects/SDL_net/) - SDL's networking extension, slightly modified. This must be installed first.
-* [Codebase](https://github.com/Ratstail91/Codebase) - generic reusable code modules
-
-## 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 GitHub wiki [here](https://github.com/Ratstail91/Tortuga/wiki).
