  Add boost license info to documentation for a few libraries.
  
    * Boost.Any: Kevlin Henney is in blanket-permission.txt
    * Boost.Variant: Eric Friedman and Itay Maman are both in blanket-permissions.txt
    * Boost.Concept: Idiana University, University of Notre Dame du Lac, Jeremy Siek,
      Lie-Quan Lee, Andrew Lumsdaine are all listed under blanket permissions.
  
    SGI and HP aren't so their license is left alone.
