samplings and submitQuery changed in order to return as a result a map with column values truncated to 255 characters and a file with the whole columns values in order to manage so to manage big data properly and the conversion of a geometry data type in a multipolygon representation applying the function st_astext(). 

GWTdbManagerServiceImpl, GxtBorderLayoutPanel and SamplingResultWithFileFromServlet classes changed in order to manage the truncated map and the file recovered from the statistical through a smp url and converted in a http url.
