Individual async texture loading is working but not very tested.
Still need some work optimizing the texture creation ( reimplement SOIL_create_OGL_texture avoiding the data duplication if not needed ).
Removed compiler warnings from zip_utils.
Fixed cTexture and cShape memory leaks ( now using std::vector by default to allocate textures on memory, removed manual dynamic loading because it's not working fine ).
Fixed cShaderProgram unloading.
Fixed a bug on cInifile.
Updated the Makefile.
Removed useless functions on Texture Factory.
Reordered load functions on Texture Factory.
Moved Draw calls to cTexture instead of Drawing inside the Texture Factory.
Added GetNumGPUs function on utils.
Renamed soil files.
Added optional compilation with LLVM.
Added TODOs, and defined the future of the developing of the library ( ordered by priority, starting the most important from the top ).
