PHP Class Vanilla\AddonManager

The {@link AddonManager} scans directories for addon folders and then maintains them in a catalogue. Addons can then be started which makes them available to the application. When an addon is started it can do the following: - Any classes the addon has declared are available via the {@link AddonManager::autoload()} method. - The addon can declare a class ending in "Plugin" and its events will be registered (TODO). - Any translations the addon has declared will be loaded for the currently enabled locale.
