ED SPARQL/Update

I've added in 1 new class and 1 new servlet to the org.icapture.ED.tag package.

-SPARQLTaggingServlet.java is a servlet that functions in the same way as TagManagerSaveTaggingServlet.java

-SPARQLTagManager.java is a java class that functions in the same way as the TagManager.java

When a user hits the submit button on ED - the javascript normally calls the TagManagerSaveTaggingServlet (passing into it all the tagging data in xml format as a parameter). SPARQLTaggingServlet will be used in the same way. Call it in the same way with the same xml. SPARQLTaggingServlet acts as Servlet wrapper for the main class which is SPARQLTagManager. It creates a Tagging object with that xml and passes it into SPARQLTagManager which processes it into SPARQL/Update (SPARUL) INSERT statements and posts them to a Virtuoso server via "http://biomoby.elmonline.ca/sparql" as parameters which are then executed.

If it is successful (determined inside SPARQLTagManager via response codes), all inserts were made successfully and it will return the ResponseCode from the Virtuoso Server (200 if successful, anything else otherwise) to the SPARQLTaggingServlet.
