- 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
- HTTP_HEADER.string does not have the ending CRLFCRLF .. but just CRLF
- WGI_RESPONSE.write_header_text has the responsibility to handle the last blank line CRLF (separating the header from the message)
- HTTP_HEADER.string does not set anymore a default content type as text/html
- added WGI_RESPONSE.write_header_lines (ITERABLE [TUPLE [name,value: READABLE_STRING_8]] mainly as an helper method,
this way the WGI user does not have to know about the CRLF end of line
