Fix for conflicts issues

Hi,

Gravity-forms-wysiwyg is conflicting with Gravity Forms advanced files uploader. (and probably others add-on for gravity forms).

To fix it, please replace the “return false;” by “return input;” at the end of the function wysiwyg_field_input in the file gf_wysiwyg_class.php.
The function must be like that :

function wysiwyg_field_input($input, $field, $value, $lead_id, $form_id) {

    if ($this->is_wysiwyg($field)) { 

        $input_id = 'input_' . $form_id . '_' . $field["id"];

        if (is_admin()) {

            $tabindex = GFCommon::get_tabindex();

            return sprintf("<div class='ginput_container'><textarea readonly name='input_%s' id='input_%s' class='textarea gform_wysiwyg' {$tabindex} rows='10' cols='50'>WYSIWYG editor</textarea></div>", $field["id"], 'wysiwyg-' . $field['id']);

        } else {

            $media_buttons = strpos($field["cssClass"], 'media_buttons') !== false;

            $args = array(
                'textarea_name' => 'input_' . $field["id"],
                'wpautop'       => true,
                'media_buttons' => $media_buttons,
                'editor_class'  => 'frontend',
                'textarea_rows' => 5,
                'tabindex'      => 0 //$tabindex
            );

            ob_start();
            wp_editor($value, $input_id, $args);
            $html = ob_get_contents();
            ob_end_clean();

            return "<div class='ginput_container'>" . $html . "</div>";

        }

    }
    return $input;
}
