[nautilus] Bring back <alt>+<num> for tab changing

[Holger Berndt <hb src gnome org>]

commit a6715be7e462109020f8450fe9781ea70e5ca128
Author: Holger Berndt <berndth gmx de>
Date:   Fri Mar 5 08:49:33 2010 +0100

    Bring back <alt>+<num> for tab changing
    
    Make the first 10 tabs of every pane changable via keyboard
    shortcuts <alt>+1, <alt>+2 etc.
    This brings back non-GUI functionality that was removed together
    with the tab menus in e156e39e07276a4de8414bfdb82340f8762060b4
    Fixes bug 609924
