[boost] A possible addition to the boost license FAQ

Hi, a question I get frequently asked is "Can I dual-license a project or a library under the GPL and the Boost Software License?". I suppose I know the answer, but I thought some of you, perhaps Dave or Beman, might have reliable wording from Devin Smith or other lawyers who participated to the license development. -- [ Gennaro Prota, C++ developer for hire ]
