Transliteration for tokens needed

Let me know how this looks.

It looks good, but 'commerce_autosku_cleanstring' should be run before converting the case, otherwise transliteration's case settings overrule autosku's settings.
Unless there is a reason behind the current order of things.

commerce_autosku.commerce.inc lines 70-80

      $sku = commerce_autosku_cleanstring($sku); //
      if ($settings['advanced']['case']) {
        switch ($settings['advanced']['case']) {
...

Thanks for the review. I can't see any reason to run the cleanstring function later. Fixed and pushed.
