the guild window opens: roster, ranks, notes and the message of the day

- the social window's third tab is live — the roster in both its views, the member card with its promote/demote/remove verbs, the rank editor's thirteen permissions, the guild information board, and the invite, leave, kick and note dialogs behind them
- setting your hearthstone at an innkeeper now asks before it takes and says so afterwards, and the innkeeper's gossip lines get their own icons back
- unavailable talents grey out, and every greyed icon in the client now goes through the same luminance fold the original used
- the buff tooltip's remaining-time line reads gold with the client's own hour/minute ladder, the macro editor takes a shift-click to paste a spell, trainer rows repaint after a purchase, and a long book page stops flickering its ellipsis
