Title: Exp/newtype physics

This converts several of the units used in physics calculations to tuple structs with overloaded arithmetic.

* `Millis + Millis -> Millis`
* `Millis - Millis -> Millis`
* `-Velocity`
* `Velocity + Velocity -> Velocity`
* `Velocity - Velocity -> Velocity`
* `Velocity * Millis -> Game`
* `Acceleration * Millis -> Velocity`
* `-Acceleration`
