PHP 5.3 compatibility hack for DB_DataObject

statusnet.links.ini file could not be read anymore due to the entry for nonce containing a comma in its key value.
PHP's parse_ini_file() function no longer allows commas in keys, and rejects the *ENTIRE FILE* if it's present, breaking various automatic joins.
