import sesame-rio-nquads package into nquads module
add log4j properties file to nquads module
replace NQuadsWriter as a thin wrapper over sesame-rio-nquads writer
fix test that relies on the NQuadsWriter expanding namespaces, when this is never necessary with the Sesame API, as namespaces are always expanded automatically inside of the org.openrdf.model.URI interface, and in addition, N-Quads has never, and will never have, any support for namespaces. If that happens it will be as an extension to Turtle, which will be separate from N-Quads as N-Quads is by design a very thin wrapper over N-Triples, which will also never have namespace/prefixes
add FIXME note about N-Quads parser catching all Exceptions
fix use of relative URLs in test1.nq that is designed to only test cases from the NQuads grammar
convert NQuadsParser to override sesame-rio-nquads parser with UTF-8 support for InputStreamReader constructor
make NQuadsParserTest pass, including always having an rdfHandler, ignoring column numbers as they are not supported, removing test for relative URL as it is not in the NQuads specification, and fixing blank node identifiers that start with a number, when the specification says they must start with a letter
fix test that attempted to parse an nquads file with no newlines in it, against the specification
