True-Fi Preference Settings EQ Tweeking

Ability for the user to see (better) & tweek the EQ settings that are applied by the Preference Discovery tool.

The resultant graph/curve applied could clickable/offer hover-over so that you can see the +/- db and frequency values that have been applied.

The graph/curve could also be editable, so the user could make small tweaks. Sometimes you might like a notch more or less of bass, or a notch more or less of treble, having spent a while with your new curve in place.
