Updating JSPs to use tag lib standard, new lams tags. Rationalising authoring down to the DHTML version (had been a DHTML and non-DHTML version). Updating URLS as per LDEV-38
made some changes to the way the authoring screen is shown. instead of having 3 separate jsp pages with 3 separate paths, combined these 3 authoring pages into the one page authorContent.jsp works the same way as the monitoring environment. removed the action forward nb_basic, nb_advanced and nb_instructions. the only forward path is now authoringContent
