Turtle: improve ordering of ontology terms

[VladimirAlexiev]

atextor/turtle-formatter#22

Currently rdfs:Class comes before owl:Ontology

• use a query to find all types of things in the ontologies
• use --subjectOrder to sort them in the best possible way

[VladimirAlexiev]

added to Makefile

  --subjectOrder owl:Ontology		\
  --subjectOrder rdfs:Class		\
  --subjectOrder owl:Class		\
  --subjectOrder rdf:Property		\
  --subjectOrder owl:ObjectProperty	\
  --subjectOrder owl:DatatypeProperty	\
  --subjectOrder owl:AnnotationProperty \
  --subjectOrder owl:NamedIndividual	\
  --subjectOrder owl:AllDifferent	\
  --subjectOrder owl:Axiom

Still need to find all types

Yes, we did this for RDFS, we should do for ttl too
Eventually this should be an item in the RDFS spec

This is still blocked by

• make frequent binary releases atextor/owl-cli#21
• prefixes trouble when using --subjectOrder atextor/turtle-formatter#27
