Slight GUI tweak for QoS order

Cambium, could you please make up your mind regarding which comes first... downlink or uplink? You guys recently swapped this, so now downlink is first, and uplink second, but you haven't changed the low or hi priority options... they're still uplink then downlink. Pick an order and stick with it! Thanks!

Agreed, Eric. We'll get this done. We want to standardize to Downlink first and then Uplink.
