Re:Authority - Sloth ships no third-party libraries of its own.

The physics engine the ragdoll runs on - PhysX, through fabmax's JNI bindings - lives in
Re:AuthCore, which this mod already requires. Its notices travel with that jar, where the
code actually is. Sloth used to carry a second copy, and two mods exporting the package
`physx` is a game that refuses to start before a single class has loaded.

What follows is not a bundled library either: no F-Tech code ships here. It is listed
because a method was taken from it, and the terms it was given under travel with the method.

    No code from F-Tech ships in this mod. What is used is the METHOD its robotic
    arms are laid out by, reimplemented here in ArmCurve: walk from the shoulder in
    fixed steps, turning the direction a little toward the hand at each one, with
    the turn rate falling as the surroundings close in. The step size, the balance
    figures and the environment probe are his, from BackpackItem.getArmPath and
    getDeltaTowardsDirection.
