Release preparation:

Remove embedded solr so that server-side of Solr is not a dependency.
  Exception in assembler if "embedded:" used.

Remove warnings from the code base and add some @Override's
Remove throws declarations of unthrown exceptions.

Remove JTS from the POM, even optional, so as not to risk inclusion in the build.
