Smiley update

[Wesley.Hardaker@sphys.unil.ch]

Well, here's pass one at a new smiley feature (what else):  smiley's
are now buttons that unhide the original smiley text.  The current
implementation has a few problems:

  It doesn't hide the graphic smiley (it should, it just doesn't
    work).
  It'll currently hide any extent it touches, which is bad (press a
    smiley face on a included text line, it'll hide the whole line).

However, its fun, and thats what matters right???
