Crafting menu can be accessed even in the dark.

But the actual crafting can't be done if it's too dark to see.
Hibernation-info

Adds a specific safety-check on entering the Hibernation part of the
food meter and provided a quick hint as to the general idea.  Thanks for
the merge-cleanup and the guidance, Kevin.  Much appreciated.

Attempted to add memorial notes for engorgement, actually entering
hibernation, and successful exit; killed a successful hibernator and
just got the msglog and an empty killcount, though.  Not sure what I
missed.
Refactor mutagen iv iuse to repeat itself less.
Add a one-time message asking player of they want to start gorging when they have the hibernation trait.
Changes as requested

Looks like these work.
Adding a pickup rule with the (Advanced) inventory item menu will ask to enable the auto pickup option if it is disabled. This adresses the possible issue with https://github.com/CleverRaven/Cataclysm-DDA/issues/4993.
"Auto pickup enabled" option can now be changed through the auto pickup manager.
Minor cosmetic changes.
