  Use "change counter" value from card (if available) for filename in cache.

The card's file cache needs a timestamp so that we know when the cache does
not match the card's content.  The solution used so far is based on
information from EF.Tokeninfo, where the time of the last modification of
the card is recorded.  However, EF.Tokeninfo does not provide sufficient
granularity of the timestamp and is not updated atomically for changes on
the card.  Some of the cards provide an internal "change counter", which is
incremented after each change of the card's content.  If such information is
available, it is used as a timestamp for the name of the card's cached file.
