Antagonists can now see what antags there are and how many + rev tweaks. (#22757)

Antagonists can now see what other types of antagonists there are and
how many in the Status tab.

Additionally, the Captain now receive this blurb when spawning in a
gamemode that contains revs:

> You are a Captain in a Revolution round!
> Remember that you are supposed to comply with all orders from SCC
Command. Although you may not spawn as a Loyalist, you are the person on
the ship that is most beholden to Central Command orders.
> This is both due to your status in the hierarchy of the SCC, and also
to allow the gamemode as a whole to work. Only very extreme factors may
justify you not joining the Loyalists. If this is the case, confirm it
with admins via adminhelp first!
