[gnome-commander/fileroller-plugin: 4/4] Adds strftime ability to file roller plugin



commit 5d22cb0a6ef1c78f65db686249a604ceec94ab2d
Author: Uwe Scholz <uwescholz src gnome org>
Date:   Mon Sep 26 22:45:16 2016 +0200

    Adds strftime ability to file roller plugin
    
    Allot of changes had to be introduced here. Basically the most changes
    are about extending the plugins configure widget and string replacement.
    
    Also a repair took place so that gcmd won't crash if the 'About' button
    in the plugin dialog is clicked.
