Added WSF_REQUEST.percent_encoded_path_info: READABLE_STRING_8
to keep url encoded path info, as it is useful for specific component
The router is now using WSF_REQUEST.percent_encoded_path_info
since URI_TEMPLATE are handling URI (and not IRI)
this fixes an issue with unicode path parameters.
This should not break existing code, and this fixes various unicode related issues related
to PATH parameter and path info
but also any component using file names.
(required EiffelStudio >= 7.2)
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)
