Sdk improvements

[Nightsd01]

• Adds a setting called kOSSettingsKeyPromptBeforeOpeningPushURL which allows developers to control what happens when a user taps a notification with a web URL. If this setting is set to true, the SDK will prompt the user with an alert asking if they want to open the website or not. By default, this setting is false.
• Adds ability for postNotification() to preprocess NSDate objects so that developers can add a delay without having to convert to strings first
• The SDK will now always convert email auth hash tokens to be lowercase for consistency
• syncHashedEmail() is now officially deprecated: added a deprecation notice.
• Removed use of private Apple API's which caused problems in rare circumstances. This private API was implemented in order to call deprecated methods for developer convenience. However we have removed this functionality in order to avoid problems with the app review process. The SDK will now print an error to the console if a developer implements these methods.
• Fixes an issue that would have caused problems parsing notifications in a new payload format.
• Fixed some issues that caused crashes in iOS 7.

    onesignal_Log(ONE_S_LL_VERBOSE, @"notificationOpened:isActive called!");
    
    NSLog(@"Notification opened with messageDict: %@, isActive: %i", messageDict, isActive);

Remove debug logging.

                     displayType:(OSNotificationDisplayType)displayType {
    NSDictionary* customDict = [messageDict objectForKey:@"os_data"];
    if (customDict == nil)

We can remove these 2 lines now if we are switching to use the elvis operator here.

NSDictionary* customDict = [messageDict objectForKey:@"os_data"];
    if (customDict == nil)
