If Simplenote can't connect to the server, it should say so in its title bar

#459 isn't done yet, and I presume it may be very difficult to do. Here's a proposed temporary workaround which might be easier to implement.

• If you start Simplenote, and it can't connect to the server:

  • It should say "Simplenote — No Internet connection" in the title bar.

• If server connectivity later becomes available:

  • The client should retrieve as many updates as possible from the server.
  • Once the client believes that it's probably up to date, it should change its title to just "Simplenote".
  • Finally, it should also show an infobar. This bar should say "Your Internet connection has been restored". It should have an "OK" button.

@unforgettableid thanks for writing up this related issue. I think it's a great idea to indicate total loss of network connectivity (though we're still probably looking at a while before being able to get it in).

It should be possible to indicate if we have a known successful connection to the server and indicate uncertainty if it's lost. On startup we should also be able to indicate until we get such a connection that the app is in "standalone mode."
