Allow capable characters to auto-eat corpses until engorged

[white_noise]

By "capable" I mean innate ability or anything of gourmand being equipped.
And by "auto-eating" I also mean auto-butchering while in auto-explore mode.

Add

  Code:

auto_butcher = very full

to your rcfile. It will butcher every corpse until you are engorged.

What if I can't eat them? Will it still butcher them through the whole game?..
