Reduce confuse duration in a few places (crate)

The older confusion durations made no sense and clearly assumed the
player would just use !curing. Orc wizards could confuse players for
over 35 turns on a lucky roll, and some spell miscast effects could
confuse the player for 60 turns.

The new standard is 5-7 turns for monster spells, gods confusing the
player, and miscast effects.
