Turnstile - Easy repeat, multi-turn quest completion

1.0.4

• Improved UI
• The panel sits beside the quest or gossip window. "Attach to the quest window" in the settings turns that off, and /turnstile panel reset puts it back.
• "Don't offer this here again" is now the small cross in the panel's corner.
• A gossip chain missing one learned option now stops and names it, instead of repeating the ones it knows.
