I finally read through all the joint code and wrote up some
documentation. I think this will be really helpful when we try to
understand all the functions in `process-drawable`, or if somebody ever
wants to import/export animations.
This switches all three games to using a new faster GOAL joint
decompressor. It is on by default, but you can go back to the old
version by setting `*use-new-decompressor*` to false.
Also fix the log-related crash, fix the clock speed used in timer math.
Decomp aligner-h, joint-h, prim-h, debug-h, game-h, penetrate-h,
bones-h, foreground-h, scene-h, script-h.
Also, has a little bit of the joint-mod-h file, but it's not finished
yet.
