Renamed "ext" folder as "contrib" folder and reorganized a little bit

Renamed any *_APPLICATION as *_SERVICE
   mainly because those components
   such as WSF_APPLICATION, renamed as WSF_SERVICE
   are not always the main application entry, and "service" describe them better
Minor implementation change in WSF_REQUEST
