* Added an extra escape code to signal "unimportant" messages. If a tree only has

  unimportant messages, it is collapsed by the default.
* Also added an optional integer argument to the escape code for opening a nesting 
  level to indicate lack of importance.  If set, the tree is collapsed by default.
