Settings / SetupWizard & OSD

- Settings cleanup and avoid segfault by not using var.
- SetupWizard simplified opening condition logic. Will only open when no
settings available
- OSD: simplified settings logic, updated translations to explain that
no type selected = all types enabled. similar to bar and monitors logic.
- Do not open changelog on a fresh install as we already open the
SetupWizard
