* pollinate, pollinate.1:
  - remove unused variable f2
  - add support for -n|--no-challenge argument
  - this technically makes it possible to use any arbitrary
    URL as an entropy server
    + e.g. random.org, news.google.com
  - document the option in the manpage
* pollinate:
  - move CURL_OPTS to the end of the line, so that the admin can override
    any curl option, such as the user-agent string in /etc/default/pollinate
