**Scr

In osx/updater/updater.go, we're referencing an ancient Go package, which has moved to a new location. Right now, the updater doesn't build (should we test this on travis?).

The visual appearance of the reconnect error page we see when there are problems with the internet connection can be significantly improved.

• Clear steps to reproduce the issue:
  Start the app without an internet connection
