Support Custom InfoWindow Tap Handling

[bleege]

The original implementation of Popups didn't bring the ability to custom respond to InfoWindow taps. Let's add this by creating a method in MarkerOptions that allows a Custom View.OnTouchListener to be set using via InfoWindow.setOnTouchListener().

After looking at this a bit further, as attractive as having the following be possible via MarkerOptions is, it's not practical as the developer will still likely need to close the InfoWindow and the primary way for doing that is via Marker. This means storing a reference to the Marker.

        // Ideal World
        mMapView.addMarker(new MarkerOptions()
            .position(backLot)
            .title("Some Location")
            .snippet("Some Snippet Text")
            .infoWindowOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View view, MotionEvent motionEvent) {
                    if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                        // No access to Marker.hideInfoWindow() or InfoWindow.close()
                    }
                    return true;
                }
            }));

        // Real World
        final Marker marker = mMapView.addMarker(new MarkerOptions()
            .position(backLot)
            .title("Some Location")
            .snippet("Some Snippet Text"));

        marker.setInfoWindowOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                // Do Custom Stuff
                // Hide It
                marker.hideInfoWindow();
                return true;
            }
        });
