Resolved #370 Tuner Editor Lock State

Resolves an issue with the previous implementation where the tuner
editor was being refreshed repeatedly to update the lock state for the
tuner, rendering the editor almost completely unusable.

Now updates only the frequency control and the sample rate control to
reflect the tuner's lock state.
