stbimage 0.2.3

!Beta Version! Will be developed! So far compatible with: stbi_load, stbi_set_flip_vertically_on_load(). Only works with windows so far!!!!! (win32/win64). PLEASE CHECK OUT THE HOMEPAGE FOR MORE INFO AND EXAMPLE. With 0.2.3 and above dlls are included so 'STBIMAGE.load_lib()' should be enough for linking shared liaries. So it's worth to upgrade 0.2.3!
