[RFC] Text Input Management System (4)

[Kazunobu Kuriyama]

The new text management system now supports the mechanism "a single key 
stroke
dispatching multiple messages".  And more, as a by-product, you can use "a
sequence of multiple key strokes dispatching multiple messages".

I think the new system now fulfills requirements for backward compatibility
in term of functionality.

Note:
(1) Although the current DefaultKeyBindings.dict could be used with the new
   system, I strongly recommend add some stuff like "Enter", "Tab", 
"Backspace",
   or whatever you like, to the dictionary file to make it practically 
useful.
   (see the head of StandardKeyBinding.dict[.gnustep]).  This is because
   the key binding mechanism of the new system is not hardwired any key 
together.
(2) Some key bindings may be consumed by OS, the window manager, or the 
windows
   of an application before the corresponding key event reaches the 
First Responder
   NSTextView.  In this case, such key bindings won't work as you 
expect, of cource.
