Update to 3.20110430. From the changelog:

  * meta: Allow adding javascript to pages. Only when htmlscrubber is
    disabled, naturally. (Thanks, Giuseppe Bilotta) Closes: #623154
  * comments: Add avatar picture of comment author, using Libravatar::URL
    when available. The avatar is looked up based on the user's openid,
    or email address. (Thanks, Francois Marier)
  * Recommend libgravatar-url-perl, which contains Libravatar::URL.
  * monotone: Implement rcs_getmtime, and work around a problem with monotone
    0.48 that affects rcs_getctime. (Thanks, Richard Levitte)
  * meta: Fix bug in loading of HTML::Entities that can break inline
    archive=yes (mostly masked by other plugins that load the module).
  * Be quiet about updating wrappers, except in verbose mode. (jmtd)
  * meta: Add FOAF support. Closes: #623156
  * Promote Crypt::SSLeay to Recommends; needed for https openid auth.
  * tag: Avoid autocreating multiple tag pages that vary only in
    capitalization. The first capitalization seen of a tag will be used
    for the tag page.
  * Fix yaml build dep. Closes: #624712
