Less spy-thief on lowpop/RP1

[Avack]

It's well-known that RP1 has a rather low population, but lately I've been noting that we've been getting a lot of spy-thief rounds there, and they've been uniformly not-very-fun in my opinion. Here's a few reasons:

1. When the game runs out of people to make spies, it can often bypass their preferences, since it requires multiple antags. Since RP1 can frequently only have two or three people on round-start, the game often has to force everyone into the role.
   
2. The spies often end up knowing who their targets are, just because there's not enough people to not be spies.
   
3. When there's nobody around, stealing stuff becomes both trivially easy and rather more damaging to the station, since nobody's around to notice the theft or to replace it/work around it.
   
4. In the case of RP1, the completive nature of the gamemode seems to favour antags who dedicate themselves to their goal than to RP, since losing focus is a good way to fall behind in items and get slaughtered by any spy more murderous than you.
   
5. Also in RP1's case, the normally long, slow rounds tend to be disrupted by losing important stuff to spy theft more than Goon2's short rounds.
   

 I freely admit that I'm not familiar with lowpop spy-thief on Goon2, so I can't speak for what it's like there, but I'd like it if a minimum player count could be imposed. 10 people, perhaps? That would make sure there were enough people to address the problems I've outlined about (except, perhaps, #4 and #5) without making it too rare on quiet days.
 I'm not sure what I would want done about #4 and #5. I'm hoping to keep an eye on it and see how I feel about it now that we're getting some more people on the RP server again.

Very interested to hear what other people think.
