Smiley track: step 1.9

The window listing the smiley is ok (F11).
The window for shortcut of smiley is in progress (F12)

So far, you can use any available smiley directly (mouse interface)
and can get a reminder of the keybinding in the shortcut window.

Yet to be done (for final step 2.0):
* Transform the keybinding into the actual mapping of the shortcut seen in
F12
* Drag & Drop from F11 to F12 windows and from F12 to F12
* Code factorisation for class ShortcutContainer and derivatives Item &
Smiley (so far, most code is shared, but actually in 3 places, should
keep only specific code in leaf-class, and main code in parent)
Revision of copyright message (so far, only a cut-paste of inspiring
previous files)
* Save shortcut-smiley mapping on exit (and reload on start)
(with protection against changing smiley-list)
