button/checkbox for "skip intro on future launches"? #23

Very nice work - but there is something I'm missing: A button/checkbox "skip intro on future launches" - that I can use to set: [[NSUserDefaults standardUserDefaults] setObject:@no forKey:@"SettingsShowTutorialOnLaunch"];

I don't like to handle this in my main view controller and I'm afraid that most of the users will not look at the settings to switch it off. So a type of "short-cut" would be nice to have right below the "skip" button!
