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.
