Version 1.02.75 -
================================
Remove dmeventd fifos on exit if they are not managed by systemd.
Use SD_ACTIVATION env. var. in systemd units to better detect systemd in use.
Do not run a new dmeventd instance on restart if there's no existing one.
Make the time window for reading fifo longer 5sec (1.02.73).
