Enhance the documentation for SimpleSAML\Locale\Language. Move all the configuration properties to the constructor, instead of the methods.

Restore the rest of the public methods in SimpleSAML_XHTML_Template that were removed, make them wrappers of the new methods, and mark them as deprecated.

Restore SimpleSAML_XHTML_Template::getLanguageCookie() and setLanguageCookie() temporarily, as wrappers over the new methods in SimpleSAML\Locale\Language.

More bugfixes. The SimpleSAML\Locale\Language::$languageParameterName and SimpleSAML\Locale\Language::$language properties should be private, and therefore not accessed from the outside of their respective classes. Add getters instead.

Add a method SimpleSAML_XHTML_Template::getTranslator() to retrieve the SimpleSAML\Locale\Translate instance local to the template, and use it to fix a bug in a template of the consent module.

Rename \SimpleSAML\Locale\Translate::t_not_translated() to the more concise (and camel caps) getStringNotTranslated().

Return lang_merge() to SimpleSAML_XHTML_Template, as it was public, and mark it as deprecated. Use array_merge_recursive() instead.

Rename \SimpleSAML\Locale\Translate::getTranslation() to the more comprehensive \SimpleSAML\Locale\Translate::getPreferredTranslation().

Make it possible to pre-load a configuration array into SimpleSAML_Configuration for subsequent calls to getInstance() to use it. This opens up for unit-testing code that calls SimpleSAML_Configuration::getInstance().

Bugfix: if an optional configuration is missing, we shouldn't register it to reuse it later (i.e. loading a config file as optional first and as mandatory later would make the second call to work -while it shouldn't-, since an empty config was loaded during the first call).

Don't gather the proxy.auth setting if we don't use it

Candidate for removal/rewrite

A template now has a translator-object, SimpleSAML_Locale_Translate.
This handles the existing translation system.

The translator has a language-object, SimpleSAML_Locale_Language. This
handles discovery and switching of locale.

SimpleSAML_XHTML_Template has several methods that are wrapped
translator-methods:

t()
isLanguageRTL()
getLanguageList()
getTranslation()

This way it isn't necessary to change much of the existing system.

(being respectful with occurences that might change the behaviour, i.e. default database prefixes)

Prevent the SimpleSAML_Logger class from creating loops while trying to get the track ID from the session. It must now be set manually by calling SimpleSAML_Logger::setTrackID(). Also allow SimpleSAML_Memcache to differentiate between a key not found in memcache and a request to memcache failed. If all servers are down, an exception is thrown and the user informed about the internal error. This hopefully resolves #264.
