STANBOL-1012: (1) Added OSGI enabled SolrResourceLoader that looksup Analyzer Factories as OSGI services (2) changed the SolrServerAdapter to use the OsgiSolrResourceLoader when creating SolrCores (3) added BundleActivator that registers all Analyzer Factories listed in META-INF/services files from the current module as OSGI services; STANBOL-1000: Changed the commons.solr.extras.icu module so that it does no longer export the org.apache.lucene.collation.* packages (as those are already exported by the commons.solr.core module)
