[boost] [BGL] trunk@63671: `detail/adjacency_list.hpp` needs to include <algorithm>

I get a compilation error in `boost/graph/detail/adjacency_list.hpp` that is fixed by adding `#include <algorithm>` to the top: /usr/local/include/boost/graph/detail/adjacency_list.hpp:1653: error: `equal_range` is not a member of `boost::graph_detail` A patch is attached.
