Replace QueueFunction and RunOOC with RunNextFrame

RunOOC never waited for combat to end; it ran its function on the next
frame. QueueFunction ran one function every 0.2 seconds. Each caller now
defers with ClassicAPI's RunNextFrame.

The loot roll announcement sends its name lists and the roll directly.
The 0.2 second spacing did not help with the server's chat flood limit
(10 messages less than a second apart), and an announcement is at most
four messages.
