Add public FieldInfo's to the model binding support

[jeremydmiller]

Today model binding only supports properties, but what about adding public fields as well? It would cut down on some code noise, especially for the Settings objects.

I haven't had a specific need for it yet, but I also don't see any reason not to implement it. If you think it will help in places, it gets a vote from me.
