add config files to make deploying easier

i use these to have it running on a custom domain (via nginx), but still
running without privileges. (as user nobody, on a higher port.)

to actually use this configuration, you'd have to have dnsmasq and nginx
installed, so i should probably write a post about that.

go/linguaevalia/etc/dnsmasq.conf

# configure a custom domain for use with nginx
address=/eval.ia/127.0.0.1

go/linguaevalia/etc/linguaevalia.service

[Unit]
Description=Lingua evalia
[Service]
User=nobody
Group=nobody
ExecStart=/home/lu/k/lp/go/linguaevalia/linguaevalia server -p 8042
[Install]
WantedBy=multi-user.target

go/linguaevalia/etc/nginx.conf

# nginx configuration as a subdomain
server {
       listen 80;
       server_name eval.ia;
       location / {
                proxy_pass http://localhost:8042;
       }
}
