Require Boost version 1.40.0 to build OQGraph (earlier versions have a bug).

storage/oqgraph/README:
  Added small README explaining the need for Boost
storage/oqgraph/graphcore.cc:
  Fix using deprecated header that is gone in recent Boost.
storage/oqgraph/plug.in:
  Change Boost detection to look for version number (patch by Sergei Golubchik).

+OQGraph storage engine
+Copyright (C) 2007-2009 Arjen G Lentz & Antony T Curtis for Open Query
+
+The Open Query GRAPH engine (OQGRAPH) is a computation engine allowing
+hierarchies and more complex graph structures to be handled in a
+relational fashion. In a nutshell, tree structures and
+friend-of-a-friend style searches can now be done using standard SQL
+syntax, and results joined onto other tables.
+
+See http://openquery.com/graph for more information.
+
+
+INSTALLATION
+
+OQGraph requires at least version 1.40.0 of the Boost library. To
+obtain a copy of the Boost library, see http://www.boost.org/
