Need to segment target output in XLIFF filter writer if TU is segmented

When using the XLIFF filter, the writer needs to generate segmented <target> if the target resource is segmented. But leave the <source> un- segmented even if the resource is segmented. This probably mean a dedicated XLIFFFilterWriter.

This was fixed during the refactoring of TextContainer, as now segment marker should be output only if hasBeenSegmented() is set.
