Sprite class and Animate Sprite class added

AnimateSprite inherits from Sprite
If you want to test out the animation just toss this code into the
bottom of the mainMenu load method
//test sprite
SDL_Renderer *renderer = nullptr;
SDL_Window *window = SDL_CreateWindow("test", 100, 100, 640, 480,
SDL_WINDOW_SHOWN);
renderer = SDL_CreateRenderer( window,-1, SDL_RENDERER_ACCELERATED |
SDL_RENDERER_PRESENTVSYNC);
SDL_Texture *tex = IMG_LoadTexture(renderer,
"Resources/Sprites/MinionSS.png");
AnimateSprite *sp = new AnimateSprite(tex,renderer, 100, 100);
int i = 0;
//sp->Down(); //uncomment 1 of these, see specific animation
//sp->Left();
//sp->Up();
//sp->Right();
while (i <10000)
{

sp->Update();
}
