I've adjusted the fetching of all of the ResultSetMetaData attributes to 
happen in one query for the entire ResultSet instead of one attribute of 
one column at a time.  I've adjusted the updateable ResultSet code to use 
ResultSetMetaData to take advantage of this, so refreshRow should be much 
faster now.
