Two minor improvements uncovered by work on upgrading between releases:
* When installing updates, make sure that securelevel <= 0.  Otherwise
  we can't remove the schg flag from files.
* When preparing to download updates, check to see if we already have
  them sitting in the /files/ directory.  This saves bandwidth if users
  run "freebsd-update fetch" more than once without installing updates
  in between.

While I'm here, bump the copyright date.
