These classes are only used in that plugin, so it doesn't make sense to keep then in Core.

Translations are now lazily loaded instead of being explicitely loaded by other components (e.g. the front controller, the plugin manager, etc...). Now other parties only configure "directories" where the translator can find translations. That makes the translator decoupled from the rest of Piwik.

Initially we considered dropping the `ini` config, but the current stance is we keep `config.ini.php` because it's a user friendly config.

refs #6753 uncommenting tests to see whether they fail. Cannot execute them directly as I am using PHP 5.3

This file is not in a class because it needs to be compatible with PHP 4.

fix tests as reports are invalidated now in some tests causing the site creation date to change causing archiving more dates

The "verbose" level doesn't exist in PSR-3, the lowest one is "debug".

fixed some integration tests. for example sometimes a converted goal was listed before the actual pageview
