Copy to system

I have added the ability that if the app is installed in /data/app for it to be moved to /system/app. A reboot is currently required for this to work. I have tried to follow your coding style and added all icons that I used that match the size of the icons you had created. The icons were pulled form the Android SDK. If you keep this feature feel free to change the icons. I have made it so if the app is installed in /system/app then this option will not appear in the setting, only if the app is in /data/app.
