Subject: [PATCH] * Source/NSWorkspace.m (-_openUnknown:): New method that
 starts an         operation system specific application for files or URL that
 could         not be handled by GNUstep applications. Based on patch by
 Julian         Mayer <julian@corecode.at>.         * Source/NSWorkspace.m    
     * (-openFile:withApplication:andDeactivate:,         -openTempFile:,
 -openURL:): Use this new method.         *
 Documentation/GuiUser/DefaultsSummary.gsdoc: Document the new         setting
 GSUnknownFileTool that allows to define a default application.
