Let me specify different screen lock timeouts while on battery vs. plugged in

[Dan Dascalescu]

When my laptop is plugged in, it means I'm at home or at work, and don't want to dim the screen.

When I'm on battery, I want to dim the screen to save power, or I'm somewhere where it might be prudent to lock the screen shortly.

Please implement this distinction in Settings -> Brightness & Lock. Windows has had it for ages.
