* libgimp/Makefile.am
        * libgimp/gimpcolorbutton.[ch]: new widget which provides a simple
        button with a color preview together with a completely wired
        gtk_color_select_dialog. Color dnd will be added next.

        * libgimp/gimpchainbutton.c
        * libgimp/gimpchainbutton.h: cleaned up the code a bit and provided
        a destroy function which takes care of freeing the memory allocated
        for the pixmaps/bitmaps (well at least I hope it does).

        * libgimp/gimpunit.c: some cases were handled wrong in
        gimp_unit_get_digits().

        * plug-ins/megawidget/megawidget.c: follow the GUI conventions when
        building the action_area and internationalized the code.

        * plug-ins/common/CML_explorer.c: fixed a typo
