remove LocaleUrlAware, cause locale adapter with download_url option do the same only better (add second localTestRepo for testing linker)
* rename Adapter::keys() to keysWithPrefix(), to get PHP5.3.8 compatibility
* FIX: change Adapter::getUrl in downloadFile to self::getUrl(), so download_url worked
* add Repository::getConfig() to get the options for adapter
* add some force params
* add reset() to some test, to prevent the RepositoryAlreadyException
* FIX: testGetUrl() to work with UrlAware and normal Repos with download_url option
