Location do not contains fields

The closure externs seem ok, but elemental does not contain Location fields (href, protocol, search, etc). https://github.com/google/closure-compiler/blob/master/externs/browser/ie_dom.js#L1252

I think this ie_dom is the one used because it is the unique place where ‘forceReload’ appears.

Current elemental2 Location class:

@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public interface Location {
  void assign(String url);
  void reload();
  void reload(boolean forceReload);
  void replace(String url);
}

@ibaca we are not using ie_dom.js; feel free send us a patch that moves more APIs from ie_dom.js but pls update the documentation similar to other ones in dom_missing_api.js. We will eventually fix them in the Closure and get rid off dom_missing_api.js.

@jDramaix I think the issue is that Location only has methods apply, reload and replace, and none of the href, protocol, search, etc. properties: https://developer.mozilla.org/en-US/docs/Web/API/Location
