[boost] [docs] Who's Using Boost link goes nowhere.

Just tried looking up that page. And the link on <http://boost-consulting.com/boost/more/background.html> goes to <http://boost-sandbox.sourceforge.net/doc/html/who_s_using_boost_.html>. First the page doesn't exist. Second I don't think pointing it to the sandbox is the right thing to do. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org
