Image capture added

Hi guys,
I've hacked a bit your project to add the ability to capture and save images.

It's a starting point (setting the resolution could be useful for get decent photos) but i love my hulk pictures

Thanks for the patch Michelle!! :)

Besides some comments that I'll inline in the patch code, I think I need to make a comment related to the still picture feature, and that was the main reason why getting pics was not on our scope for Aura: 320x240 is the maximum resolution the hardware can handle in order to apply the effects over the received images. Try something bigger that that and the viewfinder will become slow and a lot of frames will be dropped. You can try it yourself setting the Medium resolution in the code (which is VGA: 640x480).

This 320x240 can be acceptable for video (despite a bit low), but for a pic is too low, and that's we thought that getting pics wasn't really useful, and we still think it isn't.

Anyway, if you feel like like 320x240 is useful for you, we could discuss about applying your patch ;)

You don't really need to acquire the recording resources in order to get a pic. That's only needed for video because you need to get the audio recording resources. For pics, you already have the camera and the viewfinder since the app gets launched, so you don't need anything else.

Another comment to the code, not just to a single line but to a concept. Changing mode if the user wants to capture something and we are not in the proper mode doesn't seem like a good idea. It adds an undesired latency before the actual shot happens.
The best way to add the pic feature would be to add a button to change between video/still, and change the capture icon accordingly.
