Migration: zend-mvc v2 to zend-mvc-i18n

zend-mvc-i18n ports all i18n integration functionality from the zend-mvc v2 release to a single component. As such, a number of classes were renamed that could potentially impact end-users.

TranslatorAwareTreeRouteStack

Zend\Mvc\Router\Http\TranslatorAwareTreeRouteStack was renamed to Zend\Mvc\I18n\Router\TranslatorAwareTreeRouteStack. It functions exactly as the original, however, including accepting the same configuration.

TranslatorServiceFactory

Zend\Mvc\Service\TranslatorServiceFactory was renamed to Zend\Mvc\I18n\TranslatorFactory. Behavior remains the same.

Exceptions thrown by the MVC translator

In v2 releases, Zend\Mvc\I18n\Translator would throw exceptions from the Zend\Mvc\Exception namespace. It now throws exceptions from the new Zend\Mvc\I18n\Exception namespace.
