Print current level annotation when restoring

Sometimes I annotate a level with a note like "watch out, chameleon
below", which is useful to remind myself of some danger or thing to
remember when returning to the level -- but if saving and restoring on
the level itself there's no reminder of that annotation.  If you restore
on a level with an annotation, print it as part of the "welcome back"
message.
