GtkDialog sensitivity/default

[Havoc Pennington <hp redhat com>]

Hi,

This is for bug http://bugzilla.gnome.org/show_bug.cgi?id=40303, 
it's annoying to manage sensitivity/default for GtkDialog buttons.

Proposed solution appended. Comments welcome.

/**
 * gtk_dialog_set_response_sensitive:

 * @setting: %TRUE for sensitive
 *
 * Calls gtk_widget_set_sensitive (widget, @setting) for each
 * widget in the dialog's action area with the given @response_id.
 * A convenient way to sensitize/desensitize dialog buttons.
