Use transliterator_transliterate to generate "url_key"

[sreichel]

Description (*)

@luigifab had a great idea to use intl-extension for generating url key with translating all special chars. For me the PR did not work, so tried myself.

This is a non-BC-breaking try of it. It does not change method-signaturer and should be BC-safe. (I did not add all features of #1631. That could be done in another PR.)

To not reinvent the wheel for locale-mapping if have added symfony/string that exactly does what we need.

Manual testing scenarios (*)

• have multiple store with different languages assigned (eg sample data)
• edit product title to have some locale specific character/words
  • de_DE: umlauts (äöü)
  • use trademark/copyright/etc.
• generate new url-key (e.g. changing name) ...

Test product/category before and after ...

$urlKey = 'a & B, x%, ä, ö, ü';
$model = new Mage_Catalog_Model_Product_Url();
if (method_exists($model, 'setLocale')) {
    # $locale = Mage::getStoreConfig(Mage_Core_Model_Locale::XML_PATH_DEFAULT_LOCALE, <store_id>);
    $model->setLocale('de_DE');
}
var_dump($model->formatUrlKey($urlKey));

Before url-key

'a-b-x-a-o-u'

After url-key

en_US

a-and-b-x-percent-a-o-u

de_DE

a-und-b-x-prozent-ae-oe-ue

Questions or comments

Locale config in xml should be changed to not have language-specif config in core. Any ideas?

Magento already had an unsused config for it ... Mage_Catalog_Helper_Product_Url::__construct looks for Mage::getConfig()->getNode('default/url/convert'); XML.
