Add JSON-LD support and move the service loader module to api so it can
be used independent of the owlapi-impl module
lock in jackson dependency versions to suit both rdfjson and jsonld-java
Extract common superclass for the rio ontology storer factories
Start work on converting to a fully streaming parser

Just need to wrap things into an RDFHandler and then work from there
Convert RioParserImpl to stream statements through wherever possible
fix references to jsonld
Cleanup rio module
Use AtomicLong for concurrency support in gzip document sources

Removed duplicate patterns in a few places
new parser and format added to test resources

This allows the unit tests to be run successfully from Eclipse.
Not necessary for running the tests with Maven, which regenerates
them from annotations.
