ql-mythbust-liverty-v4c-h6: new hook h6

Same ad, only the opening line changed.

New opening: 'I bought one steroid cream after another, moisturizers, allergy tests and they all failed in weeks.' Banner: 'Cream after cream / your eczema / STILL?'.

Opening shots from the approved shelf; scripted checks passed (captions, banner, pause, level, pitch, text, faces, loudness).
