[PR] Make NTSO only available if a HoS has joined the round

[pali6]

...having an alternative to HoS when you want to be able to just have a bit calmer of a shift without the oppressive responsibility. NTSO is my "the shift is half over" late-join.

Why not play a sec off then? Or detective?

I guess my biggest question is how does having it as it is now hurt RP scenarios and round balance?

Not really but it'd be nice to have a HoS rather than an NTSO usually. From my ahelp experience NTSOs tend to just empty their lethals into non-antagonists or valid hunt without actual responsibility.
