#i64599#
Normaly the MediaDescriptor argument NoAutoSave indicates,
that a document must be ignored for AutoSave and Recovery.
But sometimes XModel->getArgs() does not contained this information
if implts_registerDocument() was called.
So we have to check a second time, if this property is set ....
Best place doing so is to check it immeditaly before saving
and supressingd saving the document then.
Of course removing the corresponding cache entry isnt an option.
Because it would disturb iteration over the cache !
So we ignore such documents only ...
Hopefully next time they are not inserted in our cache.
