Remove graph rewiring for now, since it's quite buggy. It will be
re-commited when ready.

Simplify range filtering, and definitely remove python filtering
    
Simplify range filtering of vertices and edges, by always filtering
both at once, even if all vertices or edges are being considered. This
severely reduces compilation time and memory, at a small potential
cost in run-time speed, which will probably be overshadowed by other
things, such as dynamic_map look-ups ("premature optimization is the
root of all evil"). Also, remove python-filtering, since, in the end,
it is just code bloat, since it is quite slow for most uses and can be
replaced, generally, by python property editing + range filtering.

	* src/boost-workaround/boost/graph/kamada_kawai_spring_layout.hpp: annotated code with openmp constructs.

	* src/graph/graph_adaptor.hh: graph_type should be a typedef to the original graph.

	* src/graph/graph_properties.hh, src/graph/graph_properties.cc: added pos_t type.

	* src/boost-workaround/boost/graph/fruchterman_reingold.hpp: annotated code with openmp constructs.

	* src/graph/graph_layout.cc: new file with graph layout routines.

	* src/graph/graph.cc: removed graph layout routines.

	* src/graph/graph_community_network.cc (struct get_community_network): fixed inversion of directedness test.

	* src/graph/graph.cc (GraphInterface::LabelComponents): use vector_property_map instead of HashedDescriptor. Don't use a static map!

	* src/graph/graph_adaptor.hh: fixed edge descriptor equality comparison, which must rely on underlying edge, regardless of whether it's inverted or not.
