Could you please add to next version of wpdt filter in column  getTitle method?

source/class.wpdatacolumn.php row 115

something like this:

    public function getTitle() {
        $titleStr =  $this->_title;
        $titleStr = apply_filters('wpdatatables_filter_column_title', $titleStr, $this->_cssClassArray);
        return $titleStr;
    }

This is crucial for column translation possibility.

thx
