Subject: [PATCH] Begin adding systemd compatibility.

The Makefile can be used to build and install rlgwebd.  On systems with
systemd, the unit file controls starting and stopping the service, and
the shell script is not needed.

The unit file uses KillMode=none because socat does not actually stop
rlgwebd, it only asks it to stop and exits without waiting for a
response.  Until a better stopping method is introduced, this setting
prevents systemd from killing all the rlgwebd processes as soon as
socat exits.
