Title: Introduces acceleration/deceleration into motion to decrease jerkyness in movements and provide more accuracy in certain situations

This ads acceleration and deceleration to movements so they don't feel jerky and so you can, for instance, accurately jump on top of blocks. What's smooth to one person is floaty to another, but the values can be adjusted.
