Add geolocation support

[velocityzen]

Right now this code never runs a callback, it is probably something with permissions.

navigator.geolocation.getCurrentPosition(function(position) {
  console.log(position);
});

Difficult. we can enable it via private headers, but we don't do that that will cause App Store submits to rejected.

- (BOOL)webView:(WebView *)sender frame:(WebFrame *)frame requestGeolocationPermission:(WebGeolocation *)geolocation securityOrigin:(WebSecurityOrigin *)origin;

But i did some research.

 ["city": "Haarlem", "country": "The Netherlands", "alt": -1.8790876865387, "cource": -1.0, "subadministrative": "Haarlem", "ocean": "", "lat": 52.3593304249772, "spreed": -1.0, "name": "Baron de Coubertinstraat 25", "countrycode": "NL", "inlandwater": "", "number": "25", "street": "Baron de Coubertinstraat", "neighborhood": "", "postal": "2037 HA", "lon": 4.66551022283385, "administrative": "North Holland", "poi": ""]
 JS: Added location 

Some technical scripting info.

// For later use.
let locationManager = CLLocationManager()
var currentLocation: [String: Any] = ["lat": 0, "lon": 0, "name": "", "street": "", "number": "", "city": "", "neighborhood": "", "administrative": "", "subadministrative": "", "postal": "", "countrycode": "", "country": "", "inlandwater": "", "ocean": "", "poi": ""]

func websiteWantsLocation() -> Void {
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation()
    print("Getting location?")
    print(locationManager.location)
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location: CLLocation = locations[0] as! CLLocation

    CLGeocoder().reverseGeocodeLocation(location) {(let myPlacemark, theError) -> Void in
        if (myPlacemark != nil) {
            let place: CLPlacemark = (myPlacemark?.first)!
            self.currentLocation["name"]   = place.name != nil ? place.name! : ""
            self.currentLocation["street"] = place.thoroughfare != nil ? place.thoroughfare! : ""
            self.currentLocation["number"] = place.subThoroughfare != nil ? place.subThoroughfare! : ""
            self.currentLocation["city"] = place.locality != nil ? place.locality! : ""
            self.currentLocation["neighborhood"] = place.subLocality != nil ? place.subLocality! : ""
            self.currentLocation["administrative"] = place.administrativeArea != nil ? place.administrativeArea! : ""
            self.currentLocation["subadministrative"] = place.subAdministrativeArea != nil ? place.subAdministrativeArea : ""
            self.currentLocation["postal"] = place.postalCode != nil ? place.postalCode! : ""
            self.currentLocation["countrycode"] = place.ISOcountryCode != nil ? place.ISOcountryCode! : ""
            self.currentLocation["country"] = place.country != nil ? place.country! : ""
            self.currentLocation["inlandwater"] = place.inlandWater != nil ? place.inlandWater! : ""
            self.currentLocation["ocean"] = place.ocean != nil ? place.ocean! : ""
            self.currentLocation["poi"] = place.areasOfInterest != nil ? place.areasOfInterest! : ""
            print(self.currentLocation)
            // will be called a thousand times or so.

            // Ok inject new java Thing! (Cool!)
            self.mainWebview.mainFrame.javaScriptContext.evaluateScript("function navigator.geolocation.getCurrentPosition(callback, error, whatever) {callback('hi')}") // Does not work
            self.mainWebview.mainFrame.javaScriptContext.evaluateScript("navigator.geolocation = {getCurrentPosition:function(call, err, we){call('hi')}}") // Does even not work
            self.mainWebview.mainFrame.javaScriptContext.evaluateScript("console.log('Added location');")
        }
    }
    currentLocation["lat"] = location.coordinate.latitude
    currentLocation["lon"] = location.coordinate.longitude
    currentLocation["alt"] = location.altitude
    currentLocation["cource"] = location.course
    currentLocation["spreed"] = location.speed
    }

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    print("Error while updating location " + error.localizedDescription)
}

The problem i got there is i can't rewrite the navigator.geolocation class.

For the rest, if you run:

> navigator.geolocation.getCurrentPosition(function(position) {
  console.log(position);
},function(position) {
  console.log(position);
});
< undefined

Then WebShell will error (in console)

JS: [object PositionError] 

I don't have a solution ready, sorry.
I'll keep on looking

Ok, i'll think i know how to fix it.
Since

navigator.geolocation.getCurrentPosition(function(position) {
  console.log(position);
},function(position) {
  console.log(position);
});

is not a listener i can directly return the values. (if i save them)
but, i will make a config flag for it, because by default location needs to be disabled.

-> Note to myself: Inject hook, and return dictionary data.
