New 'look', new skill

  There's a couple minor bugs fixed in 'look' and related commands.  Of 
  probably more interest, there is a new mud skill, 'help 
  adventuring.awareness', that is now implemented in look and related 
  commands. 
 
  Oh, and the number of looks/round is upped some.
 
  There shouldn't be any unwanted side effects, but just in case, I've made 
  copies of the old 'look' and 'llook' as 'oldlook' and 'oldllook' for this 
  boot.  If you see anything behaving strangely, check against those versions 
  of the commands, and if the new way is actively worse, let me know.
