Fixed openid when redirection is involved
Fixed Openid Attribute Exchange implementation (AX)
Added WSF_REQUEST.items_as_string_items: ... for convenience, and ease integration with other components (such as the new openid)
if True, this display verbose debug information in console
Implemented uploading of file for PUT and POST requests
Refactored LIBCURL_HTTP_CLIENT_REQUEST to free used pointer, and also ease extension of the class if needed.
Updated cURL library with addition of {CURL_EXTERNALS}.slist_free_all (..)
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
