Update Multisensor 6 firmware via Z-Stick or Z-Stick Gen5.

As a part of our Gen5 range of products, MultiSensor 6 is firmware upgradable. Some gateways will support firmware upgrades over-the-air (OTA) and have MultiSensor 6's firmware upgrades packaged as part of their platform. For those that don't yet support such upgrades, MultiSensor 6's firmware can be upgraded using Z-Stick from Aeotec (or any other Z-Wave compliant Z-Wave USB Adapters from any manufacturer) and Microsoft Windows.
