Running blissify as a systemd unit file

[mtmn]

Add an example systemd unit file for running blissify update and restart the process does any error occur.

I already have this in place

[Unit]
Description=Blissify Update Service
After=network.target

[Service]
Environment=MPD_HOST=127.0.0.1
Environment=MPD_PORT=6600
Type=simple
ExecStart=%h/bin/blissify update
WorkingDirectory=%h

Restart=on-failure
RestartSec=10s
StandardOutput=journal
StandardError=journal

[Install]
WantedBy=default.target

it was created on a whim and can be probably made as oneshot.

Is this something you would be interested in having as part of this repository? If that's the case, I can create a PR.

Hi,

It would be really nice to have it somewhere in the repo, thanks for submitting! Could you perhaps create a PR, putting the file content as well as a little description somewhere in the README? :)
