-Re: Non existent config file to 'fs -conf'

The "quiet" behavior sorta goes all the way back to the very first
import of Nutch into Apache Incubator:
http://svn.apache.org/viewvc?view=revision&revision=155829 and seems
to deal with being relaxed about not finding added resources other
than required defaults. The behavior has almost been the same for over
8 years now :-)
The quiet flag is code-settable, but the output it would produce is
pretty verbose. I suppose we can turn it on at the FsShell level,
while also making those "parsing…", etc. INFO level logs into
checked-for DEBUG level logs. Would that suffice?
