Added managers for image sprite and text sprite. Time to debug
ImageSprite and manager are mostly working. Found error in InputMan. Temporarily removed IsNewlyPressed functionality. TO DO: 1. Refactor for InputMan for IsNewlyPressed. 2. Test TextSprites. 3. Figure out why TextureAlphaMod is not working
Gave up on adding IsNewlyPressed functionality. SDL arch not really suited for it. Will find workaround later, if necessary
