Title: Changed iOS6 check for performance and convenience reasons

When using MarqueeLabel in UITableViewCell, the iOS6 check slows down scrolling
if([[[UIDevice currentDevice] systemVersion] floatValue] >= 6.0)
this way is also not 100% safe to check with. I recommend this way:
if ([self.subLabel respondsToSelector:@selector(attributedText)])

This pushes performance a little bit.
