Add a half-baked half-finished ISO Prolog syntax.

Known internal lacunae:
  * does not handle quotations correctly:
    ** fails to recognize '' as an escaped quote character (and similarly
       for other quote characters);
    ** fails to canonize quoted atoms; will fail to identify the operator
       ; from the quoted atom ';';
    ** does not contain any logic for backslash-escaped data.
  * does not implement parsing floating point numbers.
  * comments before directives get italicized.
  * way too long.  Expect some refactoring.

Known suboptimal interactions with the syntax framework:
  * parses the entire buffer at every keystroke; incremental parsing caused
    a problem at some point and has not (yet) been restored.
  * displays the entire buffer at every keystroke.
  * the incremental lexer gets confused in the presence of comments.
