Tap gesture in FLEXNavigationController's navigation bar causes buttons to reportedly become unresponsive on iOS 11 and 12 unless `cancelsTouchesInView` is turned off
Other changes:
- Editor/caller view controllers use a toolbar for the call/set button now
- FLEXNavigationController adds the Done button to it's root view controller instead of FLEXExplorerViewController
- FLEXExplorerViewController now overrides presentViewController: and dismissViewControllerAnimated: to toggle its window's key status instead of using new methods to do it
- Adds a 't' simulator shortcut to quickly present an explorer screen for testing
Provides a gesture which automatically hides or shows the toolbar on explorer screens as you scroll when you turn on `hidesBarsOnSwipe`.
UINavigationController provides this functionality by default, except that it also hides the navigation bar, and the toolbar is always shown if it has no items for some odd reason. This subclass overrides a private method (verified to exist since at least iOS 9, up to at least iOS 13) to change that.
