Subject: I'm not sure I actually coded anything worthwhile, though I
 experimented a fair bit and as usually ended up doing lots of clean-up.

Oh wait, I modified eat_from_floor prompts to only force a more if there
was actually a message before trying the inventory (whoops), and also
modified the corpses in pack hint to take into account that a saccing
player won't be interested in butchering rotten corpses.

Also implemented a modified FR 1981119: when Detect Creatures only
detects plants already seen before, print a different message
("You detect no further creatures.").
