Bug: f.lux steals the keyboard focus on startup and on notifications
If f.lux displays a notification ("you will get up in 8 hours"), then the keyboard focus is moved to f.lux. This is annoying and has no benefit.
If f.lux gets started by a scheduler (to prevent f.lux changing the screen 12hours(!) before we will have to go to bed), then it steals the keyboard focus. This has no benefit / use case, too.
