SVGHMI: Add inhibition to widget's apply_hmi_value() so that it does not change variable more frquently than given widget's frequency. This prevents flooding network with many update if browser is producing events at high rate, as for exemple when dragging ScrollBar's cursor.

<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>
