[MOD-2447] Ti.Map - Android: Map re-renders on drawer-swipe

If a drawer with a map-view in it's centerView is used and the user toggles the leftView or rightView, the map re-renders, which is not the best UX. [This SO](https://stackoverflow.com/questions/39368136/how-do-i-prevent-recreation-reload-of-mapview-inside-a-fragment) describes the same behavior natively, together with some hints to prevent it. It seems that all Activity / Fragment listeners should be forwarded to the map-view instance, so they are handled properly.
