Show level feelings at status.

  It is easy to miss the object level feeling in the mist of
the frequent messages. And having to git CTRL+F can be a
nuisance.
  Thus here the both the monster and object level feeling are
shown at the status line like this :
  LF:M-O
  Where M is substituted by a symbol for the monster feeling.
  And O is substitued by a symbol for the object feeling.
  M and O are colorized.

  Pending : add description about this to the proper help file.
  When the player does not yet have an object
feeling the ? symbol was correctly displayed,
but in the color of the object feeling.
  This provides an information the player should
not have. Now it is checked and ? is always
white.
Update dungeon.txt help file with feelings.

  A description about how object and level feelings work
has been added to the help file dungeon.txt
