[patch request] Video recording with screen off/locked

[warriorguy]

It would be nice to be able to record video and turn the screen off. It's just a waste of battery in some cases, such as using it to record an on-the-go video podcast of yourself.

Once you position the phone in a stable position and point at yourself, you're not standing behind it and don't really need the screen on draining the precious little battery life you have.
