Subject: Extend converter to RDFox rules to handle property chain axioms

The converter to RDFox datalog rules shouldn't worry about which axiom
is supported or not (it should be a job of the approximation algorithm
or of a previous step). Now the converter tries its best to convert
anything that makes sense in datalog.

Also upperbound is ready for testing.
