- Added SOIL library for image loading. Thank you to Taurinus2 for the suggestion. New zones now load. (textures are flipped)
- Integrated Tobasco's diff for Linux. Thank you Tabasco - huge help.
- Deprecated the use of the file interface library and the image loading library.
- Rewrote some of the texture documentation, debug output and 0x30 fragment handling.
- Fixed the texture crash error that prevented some zones from loading.
- Moved non Lantern related initialization into init.cpp and init.h.
- Added support for ambient light (0x2A), light source reference (0x1B) and light source (0x1C) fragments. Still not yet activated.
- Added specific categories of debug output for fragments (textures, lights, geometry...). Fragment errors will still output regardless.
- Huge cleanup to the WLD class
- Reimplemented the rending of the whole zone.
- Changelog.txt is now in the project directory.
- Added the SDL_ttf library. It is not used yet but I will commit my text on screen work in the next commit.

Known issues:
- Support for masked textures has been removed due to the new image loading library. Will have to re-add.
- A weird issue with mip masking makes far away textures have a tint to them. Still trying to figure this one out. Mip mapped images are disabled for now.
- Zone crash related to texture UV coordinates in some zones.
- Textures in Titanium zones are flipped

Priorities:
- Support for bitmap font rasterization
- Global texture animation timing
- Transparency and semi transparency with rendering (have to rewrite rendering function...again)
- Loading zone variables (sky/fog color/clip plane)
- Ambient and zone lighting
- Linux makefile
- Deprecate the current math library and introduce a new one.
