Added the ability to enable/disable via a config file;
the default is enabled for backwards compatibility.
This is an additional service, so running it the
same priority as dnsmasq, etc does not make sense.
Added USE_PROCD=1
"done" starts at "START=95", so this should start earlier
Added STOP=10 to stop syncthing early
