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)
- removed path_parameter
- added `item' to include WSF_REQUEST.item
- marked obsolete `parameter'
The goal is to remove confusion, remove URI_TEMPLATE specific `path_parameter'
and provide a way to use ctx.item (..) to also include meta variable, query, form, ... items
