paths: Add support for -q/--quiet

Suppresses output (resolved paths or "not found!") when searching a path,
similar to "grep -q".
Sample usage: hg paths -q foo || echo "there is no foo"

Just prints path names (instead of "name = result") when listing all path
definitions, like "hg bookmarks -q".
Sample usage: hg paths -q | while read i; do hg incoming "$i"; done

+    Option -q/--quiet suppresses all output when searching for NAME

     Path names are defined in the [paths] section of your
     configuration file and in ``/etc/mercurial/hgrc``. If run inside a
     repository, ``.hg/hgrc`` is used, too.
