Subject: [PATCH] Handle swap flag in msdos type labels.

* libparted/labels/dos.c (swap, raw_part_parse, msdos_partition_new)
(msdos_partition_duplicate, msdos_partition_set_system)
(msdos_partition_set_flag, msdos_partition_get_flag):  Handle the swap
flag. Set the partition type if the user sets the swap flag.
