Video recording

Pull request implements video recording for both Camera1 and Camera2 API. The Media recorder is still not configurable and it has some hardcoded values. It would be good to implement configurable MediaRecorder in the future to handle more use cases.

• Changed theme/styles so it makes more sense because Camera looks different when you can have transparent navigation and status bar on API >= 19.
• Aspect ratio is now dynamically calculated and is not hardcoded.
• Camera1Api now properly handled different preview/video/picture sizes as they are all different arrays
• Add configurable video path

There are still several issues that I found while using it on Apprologic. Do not merge this to master until I fix all issues.
