kept `key' as redirection, and also string as obsolete redirection.
Router: provide a way to pass the request methods without using manifest string, thanks to WSF_ROUTER_METHODS
so instead of using manifest array or manifest strings, just create an instance of WSF_ROUTER_METHODS
for convenience, WSF_ROUTER provides a few `methods_...' returning prebuilt WSF_ROUTER_METHODS objects
Improved code related to unicode handling in URL, and parameters (before the framework was doing too much)
Added WSF_REQUEST.path_parameter (a_name): detachable WSF_VALUE
- fill path_parameters using `import_raw_path_parameters"
when executing the route
- reset to previous value with reset_path_parameters (..),
just in case the request is executed via severals routes.
The descendant has to implement the function
response (ctx: C; req: WSF_REQUEST): WSF_RESPONSE_MESSAGE
Added related features and class in WSF_ROUTER to be able to use agent easily.
