Game Version 1.3 - update

This is most likely going to be the last update on SHAP!

- Pause option added: now you can pause the game while playing to take a break. Just press "space" or "esc".

- Texture adjustments had been done to the score:  white -> black with white outline

- Scoreboard: Since I'm still new to programming and verry unskilled I will not be able to add a scoreboard to the game. The game does not have a real score recognition, neither a winning score, it is just a counter. 

THANK YOU FOR PLAYING!
