osmdroid MapView - to follow user location

By calling enableFollowLocation() of osmdroid MyLocationOverlay, the map will center on user current location and automatically scroll as user move.

Modify MainActivity.java from the last article "Display user location by adding MyLocationOverlay on org.osmdroid.views.MapView". Call enableMyLocation() and enableFollowLocation() in onResume(), call disableMyLocation() and disableFollowLocation() in onPause(), and handle runOnFirstFix to animateTo user location.
