[Issue] Status bar style update.

[markst]

When changing the content view controller, the status bar style is not updated.

I can subclass RESideMenu and perform setNeedsStatusBarAppearanceUpdate when the content view controller changes. However if set with an animation, the reference to the contentViewContainer is not updated until the animation block is complete.

Cheers, this pull request fixes for me. Usual approach is for didMoveToParentViewController: to occur after animation is complete? Also wonder if 'UINavigationController' category should be the developers responsibility to implement, rather than implicit.

I am getting the same problem. My contentViewController (ProfileViewController) implements

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .LightContent
}

And I am doing this to show the new contentViewController:

let profileViewController = ProfileViewController()
let navigationController = UINavigationController(rootViewController: profileViewController)
self.sideMenuViewController.setContentViewController(navigationController, animated: true)
self.sideMenuViewController.hideMenuViewController()

In my RESideMenu instance I have:

sideMenuViewController.menuPreferredStatusBarStyle = .LightContent

But when the side menu dismisses, the status bar stays black.
