concealing unknown branch stairs

Browse Source 
First cut at displaying branch stairs/ladder up/down as ordinary
stairs/ladder up/down if the destination hasn't been visited yet.

Stepping on stairs with 'mention_decor' enabled, or using ':' when
already on them, will report regular stairs' destination level.
Probably not very useful since it's just N+1 for downstairs or N-1
for upstairs when currently on level N.

It's based on whether the destination level has been visited, not
on whether the stairs have been traversed, so reaching a level via
trap or level teleporation can make the level's stairs known when
their destination really shouldn't be discovered yet.
