When picking up from floor or removing from container fails because
there aren't any inventory slots available, pickup/take-out stops.
But the message
|Your knapsack can't accomodate any more items.
is inaccurate if there is gold beyond the stopping point. Actually
continuing in order to pickup/take-out gold would require substantial
changes, but varying the message to be
|Your knapsack can't accomodate any more items (except gold).
when stopping is a one line fix. The parenthesized remark is only
added if there is actually some gold after the current object and is
given regardless of whether autopickup happens to be targetting it.
