top-level string fieldcache #11

Off-heap nCache currently only offers per-segment caches. Some things are more efficient with a top-level cache (such as single valued field faceting)

This has been checked in. Performance looks good, and it avoids the faceting/sorting FieldCache insanity that currently exists in Solr. http://heliosearch.org/solr-faceting-off-heap/
