Dates are no file counters

"Avira AntiVir Rescue System 08-29-2011.rar", "Android Apps and Games
Pack 27-02-2011", "…-cable-18-08-2012-1king.rar": counterTotal read the
date as a counter (8 of 29, 2 of 2011), so the release showed a wrong
file total and counted as incomplete. Dates (2011-08-29, 08-29-2011,
29.08.2011, 02-2011) are taken out before the written-out counters are
read; [i/M] and (i/M) come first as before. Both implementations; tests;
fixtures identical.
