* cave pearls and spindleshrooms (name subject to change) now are things. Not in mapgen yet. * add the wandering "gas wisp" to light up some of the gas-filled caverns * make wisps rarely spawned by gas explosions * revamp spindlestems into a sort of mineral detector, add glowing extract bottles * optimize pngs * add gas wisps to mapgen * add spindlestems to cavern level 1, most level 1 warrens are now lit up * update internal names, adjust mineral detection range * add cave pearls to some level 2 warrens and tunnels * switch experimental simplecrafting_lib support to crafting mod * Pearls don't grow on falling nodes * put spindlestems with goblin caps, make them always grow red when near those * bunch of documentation * add castle coral to replace cave coral, which has been repurposed into column decoration * documentation for cave coral, update some locale text * add a recipe for cooking oil into paraffin * add old bones to the underworld * MIT license for bones_loot * also cook black cap gills into paraffin, they're oily * add salt crystals to the bloodthorn caverns, illuminating the floor * documentation for salt crystals * auto-generate minetestmapper colors. need to update the spindlestem colours manually * add spindlestem to fungiwood caverns too, and increase warren coverage * in anticipation of eventually adding stuff below the Slade, making glowing pit erosion self-limiting. * add a bit of displacement to the underside of the slade layer * Unique images and names for cooking recipes. * revamp bones loot * add softer footsteps for some fungus types * update mapgen_helper * update cave coral screenshot * mention glowing salts in bloodthorn caverns
