[Bug] Switching away from certain apps is not detected

[rami3l]

For several apps, Claveilleur can use AXFocusedWindowChanged to see if they are switched to, but it doesn't seem to know when they are switched away from.

Some examples include:

• com.apple.notificationcenterui
• com.apple.controlcenter

---

The current workaround is simply to first switch to another app that doesn't have this issue, and after that everything will work as intended again.

An interesting reference (if we want to implement browser tab watching somewhere down the road ¹): https://github.com/tekezo/Karabiner/blob/6181ef9c9a6aeecd4162720884fbbaa2596ee03a/src/util/AXNotifier/Karabiner_AXNotifier/Classes/AXApplicationObserverManager.m

A quick and dirty solution might be to ignore their existence at all. See: https://github.com/ianyh/Amethyst/blob/4d0e820beb25f4bdb89088326a470a9132d89ccb/Amethyst/Categories/NSRunningApplication%2BManageable.swift#L18-L37

We have temporarily excluded these apps from the observation in 5efbe89 and 8ff0dc8.

4c9a567 shows a theoretically working solution, but since the lag was prominent (cf. the commit message), the solution was not quite ideal.
