fixed lexing (syntax highlighting) of the null-character (^@) in SciTECO code

* Apparently g_utf8_get_char_validated() sometimes(!) returns -2 for null-characters,
  so it was considered an invalid byte sequence.
* What's strange and unexplainable is that other uses of the function, as are behind nA and nQq,
  did not cause problems and returned 0 for null-bytes.
* This also fixes syntax higlighting of .teco_session files which use the null-byte as the
  string terminator.
  (.teco_session files are not highlighted automatically, though.)
