Add runtime cache to zend locale data


This modified version of Zend_Locale_Data (based on version from Magento CE 1.6.2.0) uses a local cache in addition to the shared cache to prevent repeated cache requests for the same data. This can save literally hundreds of cache requests per page depending on how heavily the page uses Zend_Locale (dates and currency).
