SOLR-4658:
- Fix class name shortening issues, for SimilarityFactory's, FieldType's, and analysis factories: persisted class names' original forms are preserved in both shortened form (e.g. 'solr.TextField') and fully qualified form (e.g. 'org.apache.solr.schema.TextField')
- luceneMatchVersion on analysis factories is now persisted only when explicitly specified in the original; previously the default value was persisted when it was absent in the original
- Add MockTokenFilterFactory
