Added game screen
Modified compile.sh (but i'm not sure if it is good idea :P )
calling function, which checks user's actions
Menu is starting screen
Added buttons
Added some methods to menu
texture drawing
Button position
Sprite is drawing properly
Scaling sprite
Button pressing works fine (but gives values located relative to the desktop)
pressing works great, method gives correct values - relative to the window
Enum is in a separated file, play button works, but the code is awful. But as someone said once: "first make it work then make it work better"
