NEAT Simple Image Access Fix

There was an error in the VO Simple Image Access (SIA) server for the SkyMorph/NEAT database.  It had an error in its error handling. When an SIA call results in an error the service is supposed to return a specified XML format which describes the error. In this case the server call failed before finishing the table. This should now be fixed. While this service is located on the SkyView server (at http://skyview.gsfc.nasa.gov/vo/sia_skm.pl) there was no error in actual SkyView code.
