Reverse bad update from minetest_game

- game.conf (MAJ OK)
- default/boat/ (MAJ OK)
- craftitems.lua (MAJ OK)
- furnace.lua (not tweaked because it’s a total rewrite from
minetest_game)
- init.lua (petites modifs et remise du son/texte à la connexion de
nouveaux joueurs)
- player.lua (reprise des modifs de carbone sur l’animation du
personnage)
- tools.lua (on remet l’ancien)
- default/doors (MAJ OK, crafts modifiés)
- default/dye (MAJ OK)
- default/fire (MAJ OK)
- default/stairs (MAJ OK)

Mg, c’est à faire :
- default/textures/ (j’ai fait une bêtise, faut remettre les textures
grass/grass_side du minetest_game, et le water/water animated de
carbone)
