Add overloaded method from c++ version of SFML, like :
    setPosition(float x, float y);
    setPosition(Vector2f &position);
become :
    set_position2f(x : f32, y : f32);
    set_position(position : &Vector2f);
Update class color with operator overloading like c++ SFML.
Add more function overload,
update Vector3
