Title: [photos] Exposes `doubleTapGestureRecognizer` of `NIPhotoScrollView` as a property.

Currently, `NIPhotoScrollView` uses its delegate to allow developer to establish dependency with double-tapping zooms in and out of the image gesture.

There is a better way, available since iOS 3.2, that is by setting up the dependency between gesture recognisers through `UIGestureRecognizer`'s `requireGestureRecognizerToFail:` method.

Exposing `doubleTapGestureRecognizer` as a property allow developer to setup such dependency as they needs.
