Changed readpst and jreadpst to add extension in PstProcessor.java.  Fixed isue with generating PDFs.  

Added support for SolrCloud.  Detects if Solr Endpoint is traditional Solr or SolrCloud and adjusts accordingly.  Added solrcloud_replica_count and solrcloud_shard_count settings.  Both default to 1.  If on SolrCloud also creates an alias with ProjectName_ProjectCode.  Changed sorlID to include the project number. This is used with a SolrCloud alias pointing to multiple Collections/Projects to tell which Collection/Project the record came from.

SettingsTest updated to reflect that with MAC OS X 10.6 and above return same value as LINUX.  (Should we add a check to see if someone is using the older prePOSIX 10.5 and below?)
