[TIMOB-3198] iOS: Facebook module authorize crashes when Safari Restricted

The application crashes when you use Titanium.Facebook.authorize(); when Safari is restricted (settings->General->Restrictions).

To Reproduce

Step 1: restrict Safari via (settings->General->Restrictions)
Step 2: install app to device
Step 3: tap the 'authorize()' button

var win = Titanium.UI.createWindow({  
    backgroundColor:'#fff'
});

// need to change the APPID before you run
Titanium.Facebook.appid = 'APPID';

var fbAuthButton = Titanium.UI.createButton({
    title: 'authorize()',
    bottom: 100,
    width: 300,
    height: 60
});
fbAuthButton.addEventListener('click', function(e) {
    Titanium.Facebook.authorize();
});

var fbButton = Titanium.Facebook.createLoginButton({
    'style': 'wide',
    'sessionProxy': 'http://api.appcelerator.net/p/fbconnect/',
    bottom: 50,
    height: 30,
    width: 300
});

win.add(fbAuthButton);
win.add(fbButton);
win.open();

Tested

TiSDK 1.6.0RC1, iOS SDK 4.2, iPhone4 iOS 4.2.1

Workaround

Titanium.Facebook.createLoginButton() will still work the classic way with a window inside the app even when Safari is restricted
