// moveSelectedOptions(select_object,select_object[,autosort(true/false)[,regex]])
//  This function moves options between select boxes. Works best with
//  multi-select boxes to create the common Windows control effect.
//  Passes all selected values from the first object to the second
//  object and re-sorts each box.
//  If a third argument of 'false' is passed, then the lists are not
//  sorted after the move.
//  If a fourth string argument is passed, this will function as a
//  Regular Expression to match against the TEXT or the options. If 
//  the text of an option matches the pattern, it will NOT be moved.
//  It will be treated as an unmoveable option.
//  You can also put this into the <SELECT> object as follows:
//    onDblClick="moveSelectedOptions(this,this.form.target)
//  This way, when the user double-clicks on a value in one box, it
//  will be transferred to the other (in browsers that support the 
//  onDblClick() event handler).
