Slight changes (from Game Jam+ playtest)

I've just updated Cemetery Hill with rather minor changes (haha, I keep saying that!)

Here's what I remember (it's been about 3 months since some of these changes)

• New logo and small menu changes
• Ghosts are now invisible (for now)
• removed the gas puzzle completely.
• lowered mouse sensitivity (I plan to eventually make it configurable)
• You now MUST leave in the car to finish the game.
• slight fixes that make the game more stable
