[bijiben/wip/sadiq/modernize] color-button: Port to G_DECLARE_FINAL_TYPE

[Mohammed Sadiq <pksadiq src gnome org>]

commit edefcc577759ea0d8c234ed5fce8255d0b845bcb

    color-button: Port to G_DECLARE_FINAL_TYPE
    
    * Use G_DECLARE_FINAL_TYPE to avoid boilerplate code
    * Don't use private members.
      This class isn't derivable. So there isn't any difference
    * Also, to be consistant with gnome coding standards, use
      'self' as identifier name when referencing self.
    
    This is a part of effort to clean up codebase and make the code more
    maintainable.
