arogue5: fix some daemon-related pointer/int casting. Daemons and fuses take a single argument, nominally an int but either ignored or unsafely cast to a pointer. Its type has now been changed to void*. The save/restore code no longer tries to store this argument in the savefile. For doctor(), this is not a problem, because player is the only argument it is ever given as a daemon. However, alchemy() will fail to do anything when passed NULL. Fixing this would be complicated but possible. Summary: the code is slightly safer, but alchemy jugs are guaranteed to stop working after save and restore, instead of just extremely likely.
