fix preview and capture resolutions 

- adjust the preview so the image captured is what the user sees
- add method MySize.isSupported; current support is for full, 16:9, 4:3 and 1:1 of the highest resolution
- cleanup ImageQualityManager, add method to get the full screen resolution which is just the resolution with the largest width
- change the UI to move settings to the top and remove the auto fading
