Jump height and mouse sensitivity in main.py

Changed the jump height to 0.65. This makes it a whole lot easier to jump onto blocks.

Changed the mouse sensitivity to 0.15. Having the mouse sensitivity too much higher than this is frustrating for the user, because the view window moves too quickly.
