stop PLC before unloading


This fixes segmentation fault if service was quit without stopping it.
It has happened if Beremiz service was quit using taskbar icon or by
closing Beremiz IDE (in case of autostarted local service).

In second case to trigger the bug following step has to be done:
1. Open Beremiz IDE
2. Open project, compile and connect to LOCAL:// runtime
3. Transfer and start the PLC program
4. Open other project without disconneting the PLC runtime
5. Close Beremiz IDE

                <xhtml:p><![CDATA[This example shows how IEC program in PLC can interact with web interface. 

svgui is extensions to build web interface to PLC. It has *integrated* web-server. So it's NOT necessary to install Apache, lighttpd or nginx for that!!!

As the program is running in PLC, web UI will be available at http://localhost:8009/.


Web interface is build as SVG file in Inkscape. To edit SVG file click 'Inkscape' button in 0x: svgui extension. 
Inkscape is a free and open-source vector graphics editor. It's not part of Beremiz and needs to be installed separately.

Back_id and sele_id inputs of these blocks are IDs  of graphic primitives in SVG file. 
This is the way how elements in SVG are bound to elements in PLC program. 
You can find out or edit these IDs in Inkscape.]]></xhtml:p>
