Added profile for ES 0.90.5, rearranged pom setup.
Removed per-field cache stats (0.90 has this builtin).
FacetedDateHistogram "Collector" (Executor) shows no compile errors.
DateHistogram Facet shows no compile errors
Faceted date histogram facet bundle shows no compile errors.
Remove support for functionality not needed or not possible with 0.90.
- Hashed String Field can no longer be loaded using this hack, and is probably no longer necessary
- CacheStatsPerField is now provided by core ES
Bring faceted date histogram up to 0.90.7 (test passing).
