-- Purpose of items:
--   1) wood pick: signals that you're a noob.
--   2) mutton: signals that this isn't a vegan server.
--   3) torches: signals that you're expected to go mining where it's dark.
--   4) tinderbox: signals that you're gonna need to scavenge lights.
--   5) calendar: signals this server has seasons.
--   6) flint/steel: your purpose in life is to light trees on fire. Also, your trash. And your pet.
--   7) compass: signals an element of adventure/exploration.
