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:$ ../run/john ../test/ -inc:digits

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%.
