The new asserts in SvXMLNamespaceMap::GetQNameByKey about unknown
namespace prefixes of kde250524-4.odt etc show that those documents do
contain text:s in meta.xml without any declaration of the 'text'
namespace. Seeing as it appears to be controlled by the outside world I
changed it back to a WARN.

I also fixed (probably all of them are this) the new table export issue
in pptx
