sw: improve DOCX export of footnote separator

Don't only check the width of the line, but also the line style and the
thickness (0 is not visible).

Also there isn't a separate continuationSeparator in sw, so it should
depend on the same condition as the separator.

Unfortuantely Word doesn't support different separators per section.
