arogue5: fix some daemon-related pointer/int casting.

Browse source 
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.
