Clarify connection status on all screens

For example, when people go into configuration screens and change things that require to reconnect.

Connecting	Configure	Notification Shade

User research findings

During the usability tests of Tor VPN 0.6.2:

• 5/6 participants tried to use the Internet design Tor VPN not having a connection, often while switching between a configuration screen and the app they wanted to use. Clarifying the connection status on all screens might help.
• 2/6 participants confused "Connecting" with "Connected" in the notification shade. Clarifying the connection status with something more visual and on all screens might help.

Ideas

This is gonna require some design exploration, possibly post-MVP.
