feat(camping): add craftable tent and hammock addon

Tent pitches over a 2x3 flat footprint and lets players skip to dawn
without touching their spawn point. Hammock strings between two posts
3-6 blocks apart (straight or diagonal, +/-1 block height) and keeps
hostile mobs at bay while occupied. Both are craftable (wool/sticks and
wool/string) and mounted in all four worlds.
