Following a rather educational "game jam" using components of Tortuga, I've
made a significant number of revisions.
A brief summary:
* The entirety of the map system now have lua APIs
* The ConfigUtility handles recusive config files
* Collisions are functional
* I've added a singleton template base class, which is used by the apps
* I've decided that focusing on the engine's stability is important
* I need to push through the generated TODO list
