Namespace issues on the API (group)

api.group.getfields was returning the wrong fields (for theCRM_Mailing_DAO_Group instead of the "normal" CRM_Contact_DAO_Group ).

The fix generates a comment in CRM/Core/DAO/.listAll.php instead of overwriting the "Group" key.

The fix identified other potential problems (nothing urgent, they aren't exposed on the API anyway):

CRM_Core_DAO_Component
//NAMESPACE ERROR: Component already used . CRM_Mailing_DAO_Component ignored.
$dao['Cache'] = 'CRM_Core_DAO_Cache';
//NAMESPACE ERROR: Cache already used . CRM_ACL_DAO_Cache ignored.
