arogue7, xrogue: fix save/restore of alchemy jugs. state.c now saves the fuse that refills alchemy jugs, using the method of numbering objects previously applied to Advanced Rogue 5. Alchemy jugs that are empty when the game is saved will continue to function after it is restored. Savefile compatibility should not be affected.
