WIZKIT inventory overflow (trunk only)

Wizard mode's $WIZKIT can specify an unlimited number of items to
add to starting inventory and they'd be put there without regard to the
number of slots in use, potentially resulting in an arbitrary number of
'#' slot items.  Cap at 52 slots, same as when picking up, and put any
excess items at the hero's feet.  It's slightly tricky because the level
hasn't been created yet at the time the wizkit gets processed.
