Fix LMAlertView wasn't rotating on iOS 8+
Fix LMAlertView wasn't rotating on iOS 8+

Current implementation rotates the alert view incorrectly in iOS 8 when in landscape mode.
Same problem existed in SVProgressHUD.
Solution is taken from SVProgressHUD and works.
Solution is to check for iOS 8. In that case rotation is applied automagically.
Taken from commit 1e15c9a94bee320e7d0f94ca848dd767df494f3b on FreekSanders' fork
