fix issue #339 - duplicate feature messages

Browse Source 
while 'mention_decor' is enabled.  When stepping onto different
terrain and one or more objects remained on the new spot after
autopickup, describe_decor() was issuing its new-terrain message
right before look_here()'s similar under-the-objects message.  If
autopickup grabbed everything or there weren't any objects to begin
with, look_here() doesn't issue any dfeature (terrain) message.
describe_decor() isn't smart enought to know whether that is going
to happen.  Give look_here() a new flag argument so that its caller
can ask for the dfeature message to be skipped for the case where a
similar message has already been given.
