Dont allow to place not-fuel items in the fuel field in the furnace and dont allow to place any item in the dst field

how did this line get there?

object found *among* the stone.

That is, mese should behave such that you get something potentially useful out
of the aggregate block you just broke, rather than just collecting the whole
block when mined.

Mese crystals in stone give a single Mese Crystal when mines. Craft three of
those + 2 sticks for Mese Pickaxe, or 9 for a Mese block. Craft one Mese
Crystal by itself to get 9 Mese Crystal fragments, which all mods should use
when a full Mese Crystal is too much.

This includes new textures for the above objects, tweaks to the sounds used for
them, and naming tweaks for the textures used for default mese in stone, so
that old texture packs don't use the "wrong" image.

This represents my best effort to match C55's suggestions.

Trigger the player.lua file in init.lua

Commit the ugly and temporary test model and texture. We'll get to a real animated player mesh once the code for that is ready

Set visual_size accordingly so the player model doesn't stretch vertically (default of the sprite player)

Attempt to use the b3d model format, although it doesn't seem to work so far

Otherwise you lose 3 sand every time you have to dig up sandstone to move it.

Make steel block and brick drop themselves when digged and make them craftable back into the their materials
