Adding Coats to the Staff Officer vendor

[theselfish]

About the pull request

Title.

I am willing to toss the Tanker Jacket, as much as I miss it.
I also added the uniform to their required gear for the sake of consistency.

Explain why it's good for the game

It gives the SO more options for clothing, as it's cold on the ship.
I've also removed the free helmet they could get, for some odd reason.

Undo the helmet/hat change. Feel free to give them a regular cmcap as an option.

Uniform change fine.

Only service jacket choosable. Dress shouldn't be used regularly and tanker isn't for SOs.

The /ro cap is the same as the one they spawn with.
But, doing it as I type.

The RO's hat is, confusingly under /req.
