GOLDOBJ pickup handling (trunk only)

For GOLDOBJ configuration, relax the 52 object limit for inventory
when gold uses the special $ slot instead of a letter.  Takes care of an
old buglist entry from the beta testers.  [It will need to be revisited
if we ever implement multiple coin types that can't all fit in one slot.]

     Also for GOLDOBJ, prevents nymphs and monkeys from stealing coins,
since allowing that made their steal-item attack be a complete superset
of leprechaun's steal-gold attack.
