SVGHMI: Add list of HMI tree path in a JS array, so that we can use it for multiple purpose :
- display name of edited variable in keypads (currently wrong in relative pages)
- have some variable that hold basename of current relative page HMI_NODE's path
- propose some list of names in DropDown when selecting a relative page to jump to, without having to instancite many jump widgets.

<xhtml:p><![CDATA[This examples shows how to work with Modbus extension. It uses Modbus TCP, but the same functions are available for Modbus RTU as well. Buth protocols are supported.
Modbus extensions requires native Modbus RTU/TCP library to be installed nearby Beremiz.
Following directory structure is expected:
<Parent directory>
"beremiz"
"Modbus"
If Modbus library is installed elsewhere, then place corresponding paths
in CFLAGS/LDFLAGS in project settings.
For GNU/Linux to install Modbus library in parent directory run following commands:
$ hg clone https://bitbucket.org/mjsousa/modbus Modbus
$ cd Modbus
$ make
After that Modbus extension is ready to be used in Beremiz projects.]]></xhtml:p>
