Allow the user to enter the username/passwd

* trunk/contrib/client-side/psvn/psvn.el:
  (svn-process-filter): Some improvements to prepare the questioning for
    the password of a user
  (svn-process-send-string): Added the optional parameter send-passwd
    to suppress the display of a sent passwd
  That feature is experimental at the moment and can be enabled via
