added basic support for htmx (ajax)

- if there is HX-Request header present we sent only a part of the whole html
- we return only specific stream defined by [out ...] ezc statement
- the name of the stream is passed in the 'frame' parameter
  (if not present then 'content' is assumed)
- added ezc function: winix_is_htmx_request
