Subject: [PATCH] WPrefs: send SIGUSR2 to wmaker after saving settings

The Wayland event backend stub for send_wm_command was a no-op, so
WPrefs settings changes never triggered a reread in the running wmaker.
Now sends SIGUSR2 to the parent process (wmaker) on "Reconfigure",
causing wDefaultsCheckDomains to run and apply changes immediately.
