Menu

Added a class AltTabStopper which will stop you from alt tabing out of a
window. This is used only in the Menu class so far to stop you alt
tabbing out of the menu since it is another window over the main window
that is transparent. NOTE: if you are going to CHANGE SOMETHING i would
HIGHLY recommend you TALK TO ME FIRST. The Menu class cannot be alt
tabbed or alt-f4ed out of, thus getting rid of the buttons or not
letting show can trap you inside the game.
