make clipboard open minimal time as wxPython documentation recommends

https://wxpython.org/Phoenix/docs/html/wx.Clipboard.html#wx.Clipboard.GetData

"Call wx.Clipboard.Open to get ownership of the clipboard. If this
operation returns True, you now own the clipboard. Call
wx.Clipboard.SetData to put data on the clipboard, or
wx.Clipboard.GetData to retrieve data from the clipboard. Call
wx.Clipboard.Close to close the clipboard and relinquish ownership.
You should keep the clipboard open only momentarily."

Maybe it makes situation with pretty annoying error 'clipboard already
open' a little bit better.

                <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>
