added css classes for rendering the HTML result.
To give style to the TABLE tag, one has to define class "TABLE.query_results_table".
To give style to the TH tag, one has to define class "TH.query_results_header".
To give style to the TD tag, one has to define class "TD.query_results_data".
This way, we can change transparently the view of the SPARQL results in HTML. The same is going to be done for the case of KML (description).
