- Switched the ad component to Google's Admob, hence the extra permission "ACCESS_NETWORK_STATE".
- Added an auto pan function for the camera. Use this if your device does not support home screen swipe panning. NOTE: This function altered the "swipe smoothness" scale a bit as a side-effect, so you might have to re-adjust that setting.
- Fixed a problem on newer Androids which limited the camera's horizontal movement to half of the intended.
- Minor optimizations
