The enable_psk_passphrase_ isn't needed anymore?

[stevenjb, 2013/08/06 00:32:48]

Because we are asynchronously requesting the properties required to set
enable_psk_passphrase_, we initially assume it will be true when we layout the
View, then disable (rather than omit) the elements that do not apply. This will
typically add 1-2 lines for configured VPNs, but vastly simplifies the layout.
(Dynamic layout in Views is a bit of a pain).

When we re-factor the UI, we plan to greatly simplify this for configured VPNs.
