Wrong fieldname key in views_slideshow_cycle_views_slideshow_options_form_validate()

Hi,
In views_slideshow_cycle_views_slideshow_options_form_validate() the fieldname used as a key for the form_error() is not the good one so the wrong field is highlighted when the validation fails.

if (!is_numeric($form_state['values']['style_options']['views_slideshow_cycle']['timeout'])) {
  form_error($form['views_slideshow_cycle']['speed'], t('!setting must be numeric!', array('timeout')));
}

should be

if (!is_numeric($form_state['values']['style_options']['views_slideshow_cycle']['timeout'])) {
  form_error($form['views_slideshow_cycle']['timeout'], t('!setting must be numeric!', array('timeout')));
}

Patch to follow.
