Fix regression causing menuInteraction property not to work properly

[hugehoge]

Close #485

The behavior of menuInteraction = .swipe // or .none requires collectionView.isScrollEnabled = false.

But the menuInteraction changes call the configureMenuInteraction() directly and pass through the collectionView.isScrollEnabled = false setting.

Parchment/Parchment/Classes/PagingViewController.swift

Lines 69 to 74 in e0dc31a

	/// Determine how users can interact with the menu items.
	/// _Default: .scrolling_
	public var menuInteraction: PagingMenuInteraction {
	get { return options.menuInteraction }
	set { options.menuInteraction = newValue }
	}

Parchment/Parchment/Classes/PagingController.swift

Lines 25 to 29 in e0dc31a

	var options: PagingOptions {
	didSet {
	optionsChanged(oldValue: oldValue)
	}
	}

Parchment/Parchment/Classes/PagingController.swift

Lines 317 to 320 in e0dc31a

	private func optionsChanged(oldValue: PagingOptions) {
	if options.menuInteraction != oldValue.menuInteraction {
	configureMenuInteraction()
	}

Parchment/Parchment/Classes/PagingController.swift

Lines 332 to 363 in e0dc31a

	private func configureCollectionView() {
	collectionView.isScrollEnabled = false
	collectionView.alwaysBounceHorizontal = false
	collectionView.showsHorizontalScrollIndicator = false
	collectionView.dataSource = self
	if #available(iOS 11.0, *) {
	collectionView.contentInsetAdjustmentBehavior = .never
	}
	configureMenuInteraction()
	}
	private func configureMenuInteraction() {
	if let swipeGestureRecognizerLeft = swipeGestureRecognizerLeft {
	collectionView.removeGestureRecognizer(swipeGestureRecognizerLeft)
	}
	if let swipeGestureRecognizerRight = swipeGestureRecognizerRight {
	collectionView.removeGestureRecognizer(swipeGestureRecognizerRight)
	}
	switch (options.menuInteraction) {
	case .scrolling:
	collectionView.isScrollEnabled = true
	collectionView.alwaysBounceHorizontal = true
	case .swipe:
	setupGestureRecognizers()
	case .none:
	break
	}
	}

I move the collectionView's setting codes and add a swipe animation based on ver1.7.0 implements.
