[gimp] Keep the proxy text view from doing anything

[Michael Natterer <mitch src gnome org>]

commit 512c80cb051f522a51b5912f444ebf8ba8c0fef9
Author: Michael Natterer <mitch gimp org>
Date:   Wed Jun 24 19:26:24 2009 +0200

    Keep the proxy text view from doing anything
    
    Add GimpTextProxy, a GtkTextView subclass which does nothing but
    overriding the binding methods with empty implementations, so the text
    view has no chance of letting e.g. the display beep or doing anything
    else.
