Enable displaying item links in compatible output channels

I have announcements set to share in guild chat. I often get people asking what the item is that ive found because its just plain text of the item name. It would be great if the announcement contained the actual item so others can click to read the tooltip

Rarity sends the item name to LibSink, which handles the display in the UI. Perhaps Rarity can send the item link (which is really just a "special" string containing CSV-like escaped data) instead and it would be displayed correctly - at least in some channels? Other sinks may not support this format. Could add a checkbox to always send item links instead of just the item name and let the user select?
