App shortcuts.

If you omit the window argument of isRegistered, unregisterAll, unregister and register methods, the shortcut is registered as an app shortcut. It is active when any window of the app is focused.

They differ from native global-shortcuts because they doesn't interfere with other apps running on the same machine.

Shortcut behaviour.

If you register a shortcut for a window, this module unregister the shortcut when the window is hidden, unfocused or minimized, and automatically restore them when the window is restored and focused again.

If you register an app shortcut, this module unregister the shortcut when all windows of your app are hidden, unfocused or minimized, and automatically restore it when any window of your app is restored and focused again.
