Adopted convention name and value or values for WSF_VALUE and descendant (WSF_STRING ...)

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)
