Remove `auto_list` option

It has been defaulting to `true` for a while now. That setting provides
a nicer interface overall and there is little reason to support alter-
nate input methods.
Some prompts asking for a letter have not been adjusted, for example
evoking a rod with multiple spells. Those are hopefully gone soon
anyways.

[Committer's note: The option had no known uses except by bots, and
those could work without it. And, of course, multi-spell rods are
gone.]
