TYPO3 Core

At the moment, any language may be used for Frontend output. But in Backend, the list of supported languages is hardcoded at various places. This prevents additional languages to be defined locally, for instance when translating TYPO3 into a new language, before it is officially supported.

This patch centralizes the list into t3lib_l10n_Locales.

Adding support for Amharic (not yet officially supported) is just a matter of updating localconf.php:

$TYPO3_CONF_VARS['SYS']['localization']['locales'] = array(
        'user' => array(
                'am' => 'Amharic',
        )
);
