Automatically call spading functions when the iotm hook is triggered

[horrible-little-slime]

I'm not sure where we should put it--immediately following the announcement, in the iotm channel? in the spading itemids channel? idk.

It should always call spade items and spade skills, and should call spade familiars iff there is a specific familiar equipment whose familiar name is known (which I guess makes it sort of useless, so maybe nevermind?)
