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.
