Running Qizx XML Server as a Unix daemon

Currently qizxserver does not allow to run Qizx XML Server as a Unix daemon. On the Mac and on Linux, you may use qizxserver to configure Qizx XML Server but after that, you'll need to write the init script by hand and then install this script in the proper place.
In order to startup Qizx XML Server, your init script needs to do something like this:
(cd directory_containing_start.jar; java -Xss2m -Xmx512m -jar start.jar)
Important
Command java -jar start.jar will not work unless its current working directory contains start.jar.
In order to shutdown Qizx XML Server, your init script needs to do something like this:
(cd directory_containing_start.jar; java -Xss2m -Xmx512m -jar start.jar --stop)
