Commented Issue: listName values with ampersands cause an XML error [10087]

If a value for listName contains and ampersand, the resulting XML request is invalid because the ampersand isn't encoded as &

Add encoding logic to wrapNode.
Comments: Added an excodeXml function to fix this in v2013.02. There is an array called encodeOptionList which currrently contains only "listName". Other options can be added as needed.
