- added [query id( to get the Tk id string for the widget

  (i.e. .x6b1820.c.frame6b1b50.widget6b1b50)  This will allow people to use
  [sys_gui] to send Tcl commands to the widget in order to manipulate the
  insert cursor and the tags, among other things.

- made the [key( message work with all ASCII 127 except {  arg, I need to find
  how on earth to escape it.  Also, it would be good to support beyond ASCII
  127, i.e. accents, umlauts, etc.
