Refactored WSF_HANDLER_CONTEXT

- 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
