SOLR-4623: Fix classname shortening:
- Rename FieldType.normalizeSPIname() to getShortName()
- Stop shortening analyzer classnames
- Stop outputting analyzer classname from FieldType.getAnalyzerProperties() when the analyzer is TokenizerChain 
- In FieldType.getShortName(), tighten the set of package prefixes that will be shortened to 'org.apache.lucene.analysis.(whatever)', 'org.apache.solr.analysis.', and 'org.apache.solr.schema.'
