Review class names to use prefixes/suffixes consistently

[fjmanion]

Names of classes should be revised to use prefixes consistently. The ontology is generally pretty good about this, but absences are jarring. For instance, 'criminal justice' should be 'study of criminal justice' since it is a subclass of 'study types'. This will aid in searches and make the ontology look clearer at a glance.
