Idle Inhibitor Active on Startup

- Make killall waybar fail silently if waybar
  isn't already running
- Update launch script to run in foreground
- Use verbose version of waybar CLI args
- Automatically restart waybar if it exits
  with non 143 (SIGTERM) exit code so random
  crashes (e.g., when opening LibreOffice or
  some games) don't persist and bar gets
  restarted
