Viewer.js always defaults to Bing Imagery provider when baseLayerPicker option set to false

[cmorse]

With the following options set, Viewer.js will default to Bing Maps as the imagery provider.

var viewer = new Cesium.Viewer('cesiumContainer', {
    baseLayerPicker : false,
    selectedImageryProviderViewModel : new Cesium.ImageryProviderViewModel({
        name : 'Open\u00adStreet\u00adMap',
        iconUrl : require.toUrl('../Images/.../openStreetMap.png'),
        tooltip : 'OpenStreetMap (OSM) is a collaborative project ...',
        creationFunction : function() {
            return new Cesium.OpenStreetMapImageryProvider({
                url : 'http://tile.openstreetmap.org/'
            });
        }
    })
});

I fixed a few typos in your sample code (note it's baseLayerPicker with a capital L, the doc was wrong, fixed with #870 today)

Another unfortunate problem with the current code is that you have to create a ImageryProviderViewModel with all properties filled in, even though you don't actually need the name, url, tooltip, and you don't need the extra layer of creationFunction.

Perhaps we can add an option to allow directly specifying an ImageryProvider.

Thanks!

It would be nice to specify the ImageryProvider directly. In my case, we only want to support a single provider. I would be willing to implement that if you give me an idea of how to do it since setting ImageryProvider would probably not work with the baseLayerPicker or ImageryProviderViewModel options.

This was an easy fix so I opened the above pull request for it. Let me know what you think.

Thanks for the quick patch. I'll check it out at work tomorrow.

This worked perfectly for me
