width or width makes no sense, width or height does

A micro patch attached that changes template_preprocess_filefield_insert_widget(), because the following makes no sense:

        if (isset($action['data']['width']) || isset($action['data']['width'])) {

and should clearly be:

        if (isset($action['data']['width']) || isset($action['data']['height'])) {

Presumably this could lead to issues with presets where only a height is defined, if not fixed.
