Tim Park 8911b72d9e Add Polyline support to MapView
Summary: Per issue #1925, add support for Polyline to MapView.

Briefly, if you have a MapView declared as:

    <MapView
      annotations={this.state.annotations}
      overlays={this.state.overlays}
      style={styles.map}
      region={this.state.region}
      ref="mapView"
    />

then setting

    this.state.overlays = [{
      coordinates: [
        { latitude: 35.5, longitude: -5.5 },
        { latitude: 35.6, longitude: -5.6 },
        ...
      ],
      strokeColor: 'rgba(255, 0, 0, 0.5)',
      lineWidth: 3,
    }];

will draw a red line between the points in locations with a width of 3 and equally blended with the background.
