SolrGazetteer lacks SolrProxy configurability

[dsmiley]

SolrGazetteer configures it's Solr connection via the global "solr.solr.home" system property, which in turn is also used by other components. So basically it forces you to use an embedded SolrServer. Instead, it should be configurable similar to how I describe in issue #5 -- offer a setter to set the SolrProxy.

Needs review with upcoming changes for Solr core setup in 4.6.1...

agreed -- needs better configuration.

JVM property opensextant.solr is used to point to the solr_home, which should only be one per JVM. Use of these extraction libraries with a remote Solr server via URL instead of local solr_home is not as likely. The remote interactions mostly occur via Xponents REST interface, rather than building specific Solr plugins and interacting with Solr as the REST interface.
