Initial Jetpack and aerial maneuvers

Initial jetpack by holding down space, goes up (no ceiling)

Pressing K while in air will initiate glide, you'll be going at a much
reduced speed, enough to not kill from high height

holding Shift while in air will act as a sort of 'boost'. Minor, needs
fixing, haven't tested this w/ glide yet

Double tapping A in air will create a little dodge to the left. Need to
fix it on ground
