iOS7 Backport

This is iOS7 API backport to iOS6.

Goal

• backport useful features from iOS7 to iOS6 to simplify transition for developers without using any private API.
• backport should behave 100% same way on iOS6 as on iOS7 from developers and users perspective. For example it is ok to add implementation of -[NSTimer setTolerance:] that does nothing.
• on iOS7 back ported API shouldn't have any effect on system - default iOS implementation should be used.

Why?

Not all users will update to iOS7 and developer life is hard enaugh :)
