Allowing ||-separated multiple values in global settings

The global settings come into action whenever the corresponding entry is missing from the file. Therefore I believe they should have the same semantics as the data in the file (ie. if data is splited at ||, then the global setting should be, too).

The following patch makes it possible to enter ||-separated multiple values in the global settings. The global value is copied in the dummy field and then usual processing continues (splitting the field where || occouts).
