Release of version 0.1.2.

The Guile server support is finally meant to be a stable feature
of Serveez. We implemented a Mandelbrot computation server and client which demonstrate this functionality.
The new codec interface of the Serveez core library is now also available in the Win32 binary release. Both the new bzip2 codec and the zlib codec have been added.
Also included is an `inetd' replacement Guile script. This has been possible since the new program passthrough server came up. The new server can accept connections and pass the data transactions to a program's stdin/stdout.
