The columns in the packet list can contain various date/time related fields
like date/time captured, delta time to previous packet etc.

| num | date time                  | delta       | info
|   1 | 2012-10-02 19:00:01.123000 |    0.000000 | SYN packet
|   2 | 2012-10-02 19:00:01.223000 |    0.100000 | SYN ACK packet
|   3 | 2012-10-02 19:00:01.225000 |    0.002000 | ACK packet

When setting a time reference, it will change the time fields to *REF*:

| num | date time                  | delta       | info
|   1 | 2012-10-02 19:00:01.123000 |    0.000000 | SYN packet
|   2 | *REF*                      |       *REF* | SYN ACK packet
|   3 | 2012-10-02 19:00:01.225000 |    0.002000 | ACK packet

This will filter away important information like the delta time but it doesn't
add any value to it.

The attached patch will give the Frame Protocol Preferences to not *REF* out
the delta times, keeping the important delta time in the overview but still
able to see that the packet was time referenced:

| num | date time                  | delta       | info
|   1 | 2012-10-02 19:00:01.123000 |    0.000000 | SYN packet
|   2 | *REF*                      |    0.100000 | SYN ACK packet
|   3 | 2012-10-02 19:00:01.225000 |    0.002000 | ACK packet
