[RFC] Text Input Management System (3)

[Kazunobu Kuriyama]

The tokens used in the traditional GNUstep key binding file, i.e. Shift-,
Alternative-, and so on, are now supported in addition to Apple's.

I added some new tokens which I think are suitable for the new text input
management system.  To get the idea, see 
InputManagers/StandardKeyBinding.dict.gnustep.

For those who would like to try it, rename 
StandardKeyBinding.dict.gnustep to
StandardKeyBinding.dict.  Edit it in accordance with your preference.

To easily see how a key stroke or a sequence of key strokes, is actually 
bound to
a message in runtime, add the option --GNU-Debug=NSInputManager to the 
command line
when invoking an app.
