Subject: tdf#83877 ODF extension to write signature lines

This adds a <loext:signatureline> element to draw:image if the image
is a signatureline.

Example:
<draw:image xlink:href="...">
  <loext:signatureline loext:id="..." loext:suggested-signer-name="..." loext:suggested-signer-title="..." loext:suggested-signer-email="..." loext:signing-instructions="..." loext:show-sign-date="true" loext:can-add-comment="false"/>
</draw:image>
