Date modelType deserialization not supported in IE8

[jdjkelly]

This bit specifically:

 Ember.Model.dataTypes[Date] = {
   deserialize: function(string) {
     if (!string) { return null; }
     return new Date(string);
   }

IE8 can't parse iso8601 strings this way. One strategy is to polyfill Date.parse() to support it as described here: https://github.com/csnover/js-iso8601/blob/master/iso8601.js

And then the deserializer would become:

 Ember.Model.dataTypes[Date] = {
   deserialize: function(string) {
     if (!string) { return null; }
     return Date.parse(string);
   }

I've done this in a closed source project for my employer. I can submit a PR with the polyfill added (it's MIT licensed) - but I'm not sure that's what we want to do here? Either way, as it stands the Date type isn't supported in IE8 out of box.

Please submit a PR. It looks like @alexspeller perhaps had a solution in #204 that didn't require a polyfill.
