Height does not reflect NavBar height when it has a prompt

[onato]

If you set self.navigationItem.prompt the navigation bar increases in height. This is not taken into account by CRToast.

I guess this problem is also seen when rotating. See #73 (comment)

Damn, good one.

The code has avoided looking for a UINavigationBar in the hierarchy, but I think this kind of issue will require it.

Perhaps you can use a controllers topLayoutGuide instead?

@Ashton-W I created a branch that is able to account for this & updated the demo project with an option to add the prompt.

This does have to look in the hierarchy for a UINavigationController so this may not be the most ideal solution. Also I'm not sure if my solution will work in every instance of a prompt existing. It does seem to work for both portrait & landscape.
