No icon animation or other indication when establishing a connection

[Thomas Strehl]

On phone I'd expect some kind of indication when device tries to establish a connection.

<https://wiki.ubuntu.com/Networking#connecting>: "While Ubuntu for PC is trying to establish any network connection, the title of the network menu should be a spinner. Similarly, while Ubuntu Phone is trying to establish a wi-fi connection, the wi-fi indicator should be an animated wi-fi icon. In both cases, the item for that connection should have a spinner too. If the connection is successful, the latter spinner should be replaced by a radio mark or checkmark as appropriate."

Assigning to Ted, in the Oct 1 meeting he discussed spinners/animation as nice-to-haves he'd like to get to as time allows.

Removed the "wifi" part of title and description as this applies to GSM data connections just as well.
