The app shouldn't crash when the connection to a node fails

[faboweb]

Apparently the app crashes, when gaia can't connect to a certain node. The expected behavior is, that the app chooses a new node and tries to connect to that node.

in addition... i think we should consider refreshing the view for the user when we reconnect. otherwise, the view just displays the loading graphic and you have to refresh manually.
