WIP: Add a new set of icons for connection states and notifications

- The notification icons and status window and menu item states
  can now optionally use icons that resemble the main application icon.

  New icons for five states (disconnected, connecting, connected,
  connected_with_errors, idle_error) are loaded though we currently
  use only the first three.

  TODO: Indicate connected-with-errors state using the corresponding
  icon, and improve how states are reported when there are multiple
  connections with conflicting states.
