Fixes & Graphics Improvements!

Todays update is a couple of small changes towards my true vision of the game. The next update will be a major overhaul and will be closer to a full release of the game!

Changes:

You can now quit the game using the escape button

Crashing the plane into the ground will now close the game. (this will not be permanent)

Post processing effects have been added massively improving the graphics of the game

Multiple terrain generation changes
