tdf#135366 Save line and fill of data labels to ODF
LibreOffice has line and fill properties of data labels in charts
as loext attributes in the style of the <chart:series> or
<chart:data-point> element. For ODF there has to be a
<chart:data-label> element with line and fill properties in its
style.
This patch adds the needed <chart:data-label> elements and their
associated <style:style> elements.
The element <chart:data-lable> exists in ODF since version 1.2.
The solution requires no extended namespace. The check is adapted
in lcl_getCustomLabelField.
Import was already done in commit
