boulder pushing feedback

Redo the details about giving or suppressing "with great effort you
push the boulder".  It works the same except that if push a different
boulder than previously, you'll get a new message.  If you do it
while riding, you have the same lack-of-message for successive pushes
instead of getting a message every turn.

Don't exercise strength when pushing a boulder if poly'd into a giant.
