Done and posted. I do not agree that we should mute it all the way to
0.05% as I prefer a ballpark figure over nothing, but instead of arguing
I made it a john.conf option :-)
BTW I also dropped the "ETA:" text when we reach 100%, like this:

It's not hard tested but I think it's proper, it is tested with and
without MPI. I believe it will "catch" any malformed (or missing) config
line and default to 0.05%.
