[sslh] sslh-1.13 released!

[Yves Rutschle]

Hello everyone,

Two minor changes following user feedback in this release,
plus some more build instructions in the README. Here's the
change log:

        Write PID file before dropping privileges.

        Added --background, which overrides 'foreground'
        configuration file setting.

        Added example systemd service file from Archlinux in
        scripts/

As usual this is downloadable from http://www.rutschle.net/tech/sslh.shtml.

Cheers,
Y.
