    Allow GNOME 3 yelp to display the GParted Manual (!24)
    
    Now with GNOME 3 style help installed, running 'yelp help:gparted'
    results in this error being displayed in yelp:
        Page Not Found
        The requested page was not found in the document 'help:gparted'.
    
    Where as running 'yelp help:gparted/gparted' correctly displays the
    GParted Manual.
    
    Fix by renaming the article tag to the default 'index' that yelp is
    expecting when using the new GNOME 3 'help:' prefix.
    
    Closes !24 - Port to GNOME 3 yelp-tools documentation infrastructure
