replace() method returns void

[ajh]

The replace method is coded so that it returns the return value of the generate method (which is always void). It should probably be recoded so that it returns the actual HTMLArea object:

HTMLArea.replace = function(id, config) {
  var ta = HTMLArea.getElementById("textarea", id);
  if (ta) {
  	var taobj = new HTMLArea(ta, config);
  	taobj.generate();
  	return taobj;
  }
  else
  {
    return null;
  };
};

There's probably a better way of coding this, but this is the idea.
