Turtle: improve ordering of ontology terms

[VladimirAlexiev]

https://github.com/atextor/turtle-formatter/issues/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
