Breaking changes:

added `a_request_methods' argument to WSF_ROUTER_SELF_DOCUMENTATION_HANDLER.mapping_documentation
 added similar argument to WSF_ROUTER_SELF_DOCUMENTATION_ROUTER_MAPPING.documentation
Renamed WSF_ROUTER_METHODS as WSF_REQUEST_METHODS
Enhanced WSF_REQUEST_METHODS with new has_... function
Added WSF_ROUTER_VISITOR and WSF_ROUTER_ITERATOR that may be useful to iterate inside the router.
   we may improve the implementation of the router using those visitors in the future.
Improved the WSF_DEFAULT_RESPONSE to embedded suggested items (typically based on pseudo self documented router)
