Fixes & improvements:

• Nether brick fences support the "Tall fences and walls" setting in Minetest Game, and are interoperable with Minetest Game fences.
• Gravel sounds added to lava crust.
• Fumaroles won't extinguish nearby fires when used outside the nether.
• Improves distance fog and coloring in the main Nether area when the climate_api mod is used.

• Adds Netherrack slabs and walls
  • Netherrack Walls depend on whether the walls mod (from MTG) is present
  • Matches Netherrack recipes with Deep-Netherrack recipes, so both can craft slabs, both can craft stairs etc.
  • Likewise with Netherbrick and Deep Netherbrick
• Nether pickaxe is weakened a little against other nodes but able to mine 350 Netherrack nodes before wearing out (an otherwise hard material)
• Adds "Nether staff of Light" and "Nether staff of Eternal Light", tools which cannot be crafted and could be used instead as treasure.

Minor change: Deep netherbrick texture switched to CC BY-SA 4.0
