+Version changes:
+
+Shell drops nothing
+Simpler appletree with vi = vi + 1 optimisation, more apples
+New licences
+paramtype = "light" for light sources
+No longer override day night ratio on joinplayer to avoid darkness
+Set SPAWNEGG in functions.lua to enable spawnegg spawning in moonrealm
+Moonrealm mese glows and drops default:mese
+Shorten lines, cleanup code, fix undeclared globals
+Noise objects created only once
