[tracker] Make search entry grab focus on Ctrl+S

[Carlos Garnacho <carlosg src gnome org>]

commit a56b17760616a476ca487c11408d5c2244901853

    Make search entry grab focus on Ctrl+S
    
    Now TrackerEntry implements GtkActivatable, grabbing focus in this case.
    Since there is no GtkAction interfacing, a new GtkAccelGroup has been added
    to the main window to deal with this.
