* [DH_WALK,FIX] Use rdf_datatype/3 to interpret integers in SPARQL COUNT results.
* [DH_WALK,FIX] Taking a random step on the LOD cloud fails for blank nodes and literals; also for dereferences that cannot be interpreted as RDF.
* [DH_WALK,EXT] Changed the way in which LOD walking is cached locally: all dereferences are now loaded locally. This means that everything needs to be garbage-collected now, if a certain number of triples is reached.
