Puzzle Path Simple Menu

I moved and modified the original Game1.cs portion of
PuzzlePathDimension into the GameScreen.cs. I added a Screen Class and
GameScreen, TitleScreen, and ControlScreen are derived from it. This
version only recieves input from a xbox 360 game pad or keyboard.
Updated for Mouse Input and Different Screens

A simple way to detect mouse, not very efficient.
