[PROBLEM] moOde does not appear to notice when ashuffle fails to start

[cricalix]

As a thought for the whole startup and being able to get the status - ashuffle ships with a default systemd config that can be used as a system level config instead of a user level config (https://github.com/joshkunz/ashuffle/pull/75/files).

I've done a quick test that proves that this systemd config works. Putting in the filters etc via the override.conf feature of systemd should hypothetically work; the override just rewrites the ExecStart with all the additional bits.

Once the service is started, the status can be checked easily enough with systemctl status ashuffle.service or systemctl is-active ashuffle.service, and on failure (which could then potentially be passed to the web ui?), the status looks like:

Code:

● ashuffle.service - Shuffle service for mpd
