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_STRING.is_empty
Improved HTML_ENCODER to be able to decode a STRING_8 or STRING_32 using general_decoded_string (s)
Improved tutorial example
Added precompilation for WSF library
Cosmetic (removed unused locals)
So this is really more flexible this way, and much easier to write application supporting CGI, FCGI, Nino and so on .. as demonstrated in hello_world
This is a first version, more will come later, mainly migrating from Eiffel Web Reloaded to this Eiffel Web Framework project.
