    files-view: adapt rename entry length
    
    We are having some problems given that the rename entry
    is kind of small for some file names, and that makes the
    rename popover vs inline renaming kind of a problem.
    For that, increase the default entry length and adapt
    for longer names with a MIN/MAX length.
