Update of https://odfvalidator.org/

[Regina Henschel]

Hi all,

Michael has listed in his summary of ODF 1.3 implementation some changes 
for the validator, especially I read "Support 1.3 in web validator".

But https://odfvalidator.org/ has no item for ODF 1.3 and automatic 
detection fails for ODF 1.3 too.

When is support for ODF 1.3 supposed to work? Is there an instance where 
support for ODF 1.3 can be tested in advance?

Kind regards
Regina
