Decompile joint, collide-func, clean up joint decompression code for all games (#3369)

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.
