[bijiben] Implement initial custom color palette for Notes color dialog

[Pierre-Yves Luyten <pyluyten src gnome org>]

commit b035ab66bf4f25b89c5c6de9f69aafcbb1643b17
Author: Pierre-Yves Luyten <py luyten fr>
Date:   Sun Dec 2 03:03:07 2012 +0100

    Implement initial custom color palette for Notes color dialog
    
    BjbColorButton just overrides gtk color button
    to use add_palette
    Colors palette is not yet decided
    This commit still relies on standard gtk color chooser dialog
    See https://bugzilla.gnome.org/show_bug.cgi?id=689143
