Backend: Active Sessions

[shuvashish76]

Show list of devices and applications that are logged into your account. Along with #1647 (2FA) this is also another security feature request useful to keep track of your logged in devices. In case you logged in a private/outdoor device temporarily & forgot to logout there then currently there are no ways to logout from that device besides having that device physically, which I feel is really insecure.

• Show "Active Sessions" (IP, location & browser or app version for each logged in device)
• Option to remove them from any of your logged in device.
• Option to "Terminate All other Sessions" (logs out all other devices except for this one)
• Show a message on your account ACTIVITY each time you logged in a new device.

I could see this being handy but not especially so. When we run out of feature parity improvements to the news reader, we'll get to this.
