Support Dalamud self-tests

[redstrate]

This isn't necessarily useful but may serve as interesting goals:

• "Test FateTable"

  • Looks like the fate table test is fairly simplistic, I think it's just checking to see if the fate actor table isn't empty

• "Test Item Payloads"

  • because we can't add the item id 2003363 to our inventory (it's a quest key item)

  • Collectables aren't supported either
• "Test MarketBoard"

  • The marketboard test will be more involved, it looks at item history, has you buy an item, finding the cheapest item, and then talking to a retainer to view tax rates

• "Test Party Finder"
• "Test DutyState"
• "Test Target"

  • Oh, we also fail "Test Target" because we don't yet implement soft targeting (CT 4)
