DDF-427 Update Solr to 4.7.2

- Embedded spatial4j and removed old spatial4j bundle from features
- Removed forked version of Lucene Spatial Extras (LSE) and the use of
  the brute force GeometryFieldType 
- Removed use of dynamic imports that are no longer used for extensible 
  metacards but caused issues with Solr 4.7 and blueprint
- Removed WKT normalizer since Spatial4j determines date line crossing
  by width instead of polygon line direction
- Enabled international date line and geometry collection unit tests
