Virtual objects only for visualisation

For now this filter only work for TP-UART connection modes, I'll check if it can be added for Routing as well.

It works also in Routing mode. I checked this on my installation I have LM4 and LMLB connected via KNX IP and when I did things which I mentioned above it works fine. I saw only telegram on LM4 and not on LMLB. But when I disable the filter TP>IP telegram is appearing on both busmonitors.
