Auto stop recording on low battery level.

[Markus]

Wouldn't it be nice to have a rec auto stop on low battery? You loose the recorded material if you run out of battery whilst recording raw (Not sure if the same applies to h264). Preferably this would be a function you could enable/disable and choose at what battery level you would like it to auto stop.
What do think? Possible/Useful?

Makes sense, and it's very easy to implement. Who's going to try?
