TC-4653 : Add access to iOS App Setting URL

Add access to the iOS8 UIApplicationOpenSettingsURLString. This allows the developer to launch directly into the iOS8 App Settings Screen using Ti.Platform.canOpenURL.

For example:

~~~
var settingsURL = Ti.App.iOS.ApplicationOpenSettingsURL;
if(settingsURL!=undefined){
	if(Ti.Platform.canOpenURL(settingsURL)){
		Ti.Platform.openURL(settingsURL);
	}else{
 	alert('cannot open URL');
 }
}

~~~

[TIMOB-17640] Adding and updating UserNotification methods

- remoteNotificationsEnabled calls isRegisteredForRemoteNotifications on iOS8 and up
- enabledRemoteNotificationTypes calls currentUserNotificationSettings on iOS8 and up
- method name change registerForLocalNotifications ---> registerUserNotificationSettings
- registerUserNotificationSettings types ---> takes an array
- new property ---> currentUserNotificationSettings
- notification constants in Ti.App.iOS are prefixed with USER_
	- eg. NOTIFICATION_TYPE_BADGE ---> USER_NOTIFICATION_TYPE_BADGE
	- To avoid confusion with similarly named constants in Network.
- TiAppiOSNotificationCategoryProxy ---> properties are creation time only
	- identifier is readable after creation
