Fixed gui and key event works correctly

Hi Guys, I fixed the gui by ensuring that the GameWindow has the focus and only the GameWindow has the focus.  But in your own project this is what you have to do:

Click on the New Game button, go to its property and search for "Focusable".  Then UNcheck the Focusable checkbox.  Do this for the combobox (the one that has the levels), the high score button, and the apples eaten label, and everything else EXCEPT for the Game Window.  Make sure that the GameWindow has the focus and make sure that its Focusable is Checked.
