SVGHMI: add support for multiline widget declaration using svg:desc.
Declaration started in inkscape:label and interupted by a '\' can be continued in the description field.
After an empty line, the rest of the description field is left for description text.

<xhtml:p><![CDATA[This examples shows how to work with BACnet extension.
Extensions requires native BACnet stack to be installed nearby Beremiz.
Following directory structure is expected:
<Parent directory>
"beremiz"
"BACnet"
If library is installed elsewhere, then place corresponding paths
in CFLAGS/LDFLAGS in project settings.
For GNU/Linux to install BACnet library in parent directory run following commands:
$ svn checkout https://svn.code.sf.net/p/bacnet/code/trunk/bacnet-stack/ BACnet
$ cd BACnet
$ make
After that BACnet extension is ready to be used in Beremiz projects.
BACnet stack implementation contains a lot of test tools. They could be useful during
debugging and BACnet investigation. See "BACnet/bin/readme.txt" for more information about them.]]></xhtml:p>
