Velbus protocol update

Hello everyone,

Well, here we go again with another Velbus protocol update.

Version 1.3.0 is now available to download from the GitHub HowTo page.

https://github.com/openremote/Documentation/wiki/Velbus

This version supports the new VMBMETEO Weather station and VMBDMI-R dimmer.
While also adding the 1st generation VMB1TS temperature sensor.

There is also an extended function for the counter_status and counter_instant_status commands.

By adding a value to this command, for example

1:0.5

wind:0.964

light:0.25

You can either convert the incoming value or simply error correct the displayed value.
