This hook allows modules and extensions to scan for settings in additional folders.
The Settings subsystem provides metadata about many of CiviCRM's internal settings by scanning for files matching "settings/*.setting.php" (e.g. settings/Core.setting.php).
This hook was introduced in CiviCRM v4.3.0 and v4.2.10.
