    EogWindow: Restore the code to update the recent files list
    
    This partially reverts 94ceb3d5679c89a099717c3b7dc741c0558c1adb
    where the code to update the recent files list was removed together
    with the corresponding menu entry. Turns out the code was still useful
    for the recent files list in Nautilus.
