mandos-keygen: Generate "checker" option to use SSH fingerprints.

To turn this off, use a new "--no-ssh" option to mandos-keygen.

* INSTALL (Mandos Server, Mandos Client): Document new suggested
                                          installation of SSH.
* Makefile (confdir/clients.conf): Use new "--no-ssh" option to
                                   "mandos-keygen".
* debian/control (mandos/Depends): Changed to "fping | ssh-client".
  (mandos-client/Recommends): New; set to "ssh".
* intro.xml (FREQUENTLY ASKED QUESTIONS): Rename and rewrite section
                                          called "Faking ping
                                          replies?" to address new
                                          default behavior.
* mandos-clients.conf.xml (OPTIONS/checker): Briefly discuss new
                                             behavior of
                                             mandos-keygen.
* mandos-keygen: Bug fix: Suppress failure output of "shred" to remove
                 "sec*", since no such files may exist.
 (password mode): Scan for SSH key fingerprints and output as new
                  "checker" and "ssh_fingerprint" options, unless new
                  "--no-ssh" option is given.
* mandos-keygen.xml (SYNOPSIS/--force): Bug fix: Document short form.
  (OPTIONS/--no-ssh): New.
  (SEE ALSO): Add reference "ssh-keyscan(1)".
* plugins.d/mandos-client.xml (SECURITY): Briefly mention the
                                          possibility of using SSH key
                                          fingerprints for checking.
