Clearer instruments and a safer tack.

Stale values show --- instead of a frozen or fake 0. Choose depth below transducer or keel, magnetic or true heading, and rudder. Confirm before you tack, or hide the tack buttons. Voyage recording can pause. Map memory and follow-me are more stable.

Works with any 3.x hub. Update the hub to 3.3.7 for keel and true heading from the boat, and smoother Bluetooth.
