v0.9.1

Fixed

• The panel's transcript buttons - "watch the live transcript" and the per-attempt "transcript" link - and both unblock buttons did nothing when clicked. Each built its onclick attribute by splicing JSON.stringify(...) straight into a double-quoted HTML attribute; JSON.stringify's own quotes closed the attribute early, leaving onclick holding invalid JavaScript. The value is now HTML-escaped before it goes in, matching every other attribute the panel builds this way.
