Title: Xenoarch: artifacts, strange rocks, pretty orebox

Artifacts and strange rock formations spawn during world gen. Frequency
may need tweaking.

Strange rocks melt when acid hits them due to what I assume are changes
/tg/ made with how acid works. Alternately I missed something during
copypasta spree. I'll muck with it later. For now, harvesting always
works with applied welding tools.

Ore boxes back to old beautiful selves. Re-added a few icons to
mining.dmi and the strange rock icon to turfs.dmi
