Fixed small bug in geocoding code.
Updated the demo page to include build information.
Fixed wrong version of modernizr
* Added support for reading options from a file

Default initialization options can now be saved in file called
defaults.  Format is json e.g.
{
        "MapService": "OpenStreetMap",
        "GeocodeService": "Nominatim",
        "ViewerState": "$view$=5&$facet0$=virtcxml:FacetAltitude"
}
Added an alternative image controller

Simple images such as jpgs can be used instead of deepzoom images.  Just
specify a different image controller:

ImageController: new PivotViewer.Views.SimpleImageController()

See the simpleimages.html example
Fixed typo
Added loader for collection data in json format

e.g.
Loader: new PivotViewer.Models.Loaders.JSONLoader("samples/data/nigeria_state.json")
