README: indicate Solr(J) 4.4 is the known version
http_solr_server is the new name for streaming_update_server and query_server
remove useJavabin! method as there is no such beast for SolrJ 4
remove meaningless queue_size as streaming update server can't be used
remove meaningless num_threads as it was never used anyway
version 1.0.1: it's now called http_solr_server, get rid of useless stuff
