fix up the rest of the GL code, add glew to project, add makefiles for opengl, fix makefiles so that it can be built with gcc, update project files to automatically output to the build directory

change names, fix some bugs, minor GL/D3D fixes, update tests, fix effect files, output a little more debug information

update graphics subsystem code to add mipmap support and also add initial GL texture stuff and helper functions

fixed some more alignment issues for SSE usage (maybe I should cut donw the size of the align function)
