Clear notification when connected to Internet

[ylogx]

Having the notification lying around when the user is clearly connected to Internet is useless and intrusive. Desired Result: The notification disappears after sometime when the user is logged in and appears back on when user gets disconnected.

Current Situation: The notification stays forever once connected to a loginable network.

We should poll in the service at 5 minute intervals, ping some server (Google probably) and check if we're connected to Internet. If true, clear notification, else if false check if we need to show notification.
