LPBUG#906638 : Fixes to build oqgraph with boost 1.48

- dijkstra_shortest_paths() needs a Graph as first parameter, in case of reverse_graph we now need to use
  its m_g member
- use boost::tuples::tie() on all places where tie() was used . Reason -
  fix the build with Visual Studio 10 SP1 (which includes std:tr1:tie, thus creating  ambiguity)
