//helppane.js Version 1.8
//Only minimal adaption for use in the NTC project - GMM
//added DoGlossary for special NTC glossary direct call behaviour - MWT
//nb that Glossary behaviour requires mods to helppane.aspx as well
//added DoSpecificHelp(sTopic,nHelpType,sHelpPath) to allow override of
//relative path to help file by caller (fixing bugs 4,894,1007) - MWT
//Fixed path bug in DoSpecificHelp -DJB
