Don't show the "lost session" dialog right away

[GregM]

If the Vault GUI is set to connect automatically with a profile, it would be really nice if it would attempt to reconnect when the session expires, and continue with the requested operation, rather than putting up an error dialog and then forcing a repeat of the operation. If the automatic reconnect fails, then *that* would be the time to put up the error dialog. For people who want to know that the session was lost, this should still be logged in the messages pane.

I'll add your vote to this feature request. We can easily enough re-login automatically, but because of the way it was designed, it would be hard to continue the operation that was started, and that is probably the part of this that matters most.
