Upstream changes:
2010-03-13 - Release 0.94 - Jarkko Hietaniemi  <jhi@iki.fi>
	* Address rt.cpan.org #43580:
	  "Reversed logic on overload::StrVal() in \ 
AdjacencyMap::Vertex::__set_path"
	  Had to add a new option, refvertexed_stringified.
	* Address rt.cpan.org #50210:
	  "Graph-0.91: bug in unionfind parameter"
	  One cannot delete from a unionfind graph: now enforcing that.
	* Address rt.cpan.org #48090:
	  "all_reachable on directed $g->add_edges(['a','b'],['b','a'])"
	  Now if there are loops, all_reachable() will include
	  the initial vertices themselves.  Also all_neighbors()
	  had some problems in certain cases, fixed those too.
	* Address rt.cpan.org #50210:
	  "Graph-0.91: bug in unionfind parameter"
	  One cannot delete edges or vertices from a unionfind
	  graph: now enforce that in code.
	* Address rt.pcan.org #42549: "stron"
	  Document that strongly connected components will include
	  isolated and sink and source vertices.
