[PR] Implements a limit to how much can be eaten at once.

[Zamujasa]

speaking as a player and not an admin (impossible, i know) being able to spam devour shit with the use button is hilarious. someone tried to remove this before by adding an action bar for eating (!?!?) and opinions of it flew like a brick

the new mob critters in general are extremely active with eating random shit, limiting them (and ghost critters, by extension) would probably be good
