Buggy sort order in Mountpoints management

[prl]

In MENU>Setup>Network>Mount manager>Mountpoints management, the primary key of its sort order is (effectively) the Python id of the mounted/unmounted picon, and then the mount name is used as the secondary key. The ids of the icon Pixmaps are not under programmer control, and while ordering by mount status as the primary key is not necessarily a bad thing, the order is arbitrary, and the ordering in MENU>Setup>Network>Network browser is by mount name (within a single server’s exported mounts list).

Replication

With at least two enabled FSTAB mounts in Network browser (avoiding AUTOFS mounts because of the complications of bug #744), disable one of the mounts. Its sort position will change.
