JRH Elves

Worlds from older versions carry over: items in elf shops, elf gear and wagon and ship cargo are upgraded on load.
New artwork for every high elf, the guards, the elf spawn eggs and the rune stone. Each townsfolk profession now carries its own tools, and blacksmiths have their own working look.
Elves and guards have their own voices.
Guards are much tougher (40 health, 8 armour), now fight wardens and ghasts, hold their spears the vanilla way and stab with them, and hold their bows in the hand.
Guards from older saves heal to full once when the world is loaded.
Hostile mobs no longer spawn naturally inside elven towns and colonies or within 32 blocks of them. Peaceful animals still spawn there.
Founding a colony is spread out over time to cut down on lag spikes.
