Quote marked text into your message

To answer a single sentence of an agent's message, mark it in the conversation: a small Quote button appears beside the marking. One click puts the text into your message in quotation marks, followed by a dash, with the cursor right behind it, so you can type your comment at once. Each further quote gets its own line, and with the cursor in the middle of your text, the quote goes into the line right after it. It works on your own messages too, on every card and in Obeya's sidebar.
