Objects can be set down and picked back up

The engine always knew how — dropObject and pickUpObject were in the
command set from the start — but the table never offered a hand for
it. Now selecting a magic stone (or any object card) on your turn
shows a "Drop it here" button in the hint bar, and standing on a
square with objects lying on it offers a "Pick up <name>" stamp per
object, disabled once your actions have ended (picking anything up
ends them, per the rulebook). The chronicle narrates both.
