Currently the XenForo logo instead of the FreeBSD orb is used for the
apple-touch-icon and og:image on https://forums.freebsd.org.
This looks bad in Firefox' Top Sites view and also pretty bad on iOS.
It's also used on Twitter, Facebook, and probably other sites when
links to the FreeBSD forums are posted.
Essentially we're doing free advertisement for XenForo instead of for FreeBSD.
See the forum link for an example screenshot.
fixed, see https://forums.freebsd.org/threads/63736/
