Added support to upload/modify sub texture to Renderer interface introducing a new method:

    public void modifyTexture(Texture tex, Image pixels, int x, int y);
Implementations added for LWJGL and JOGL. LWJGL seems to work. JOGL is untestet. Android implementation needs to be done by someone else (but is already prepared for).
