[MERGED PR] Makes security slots scale at lower population

[RubberRats]

Lowpop really doesn't need more than three officers, in my opinion. If a lone antagonist has reached the point where they need a full team to deal with them, it's usually because they were allowed to snowball with little to no resistance. I have really only seen this in cases where there was maybe one (if you're lucky) extremely passive officer. Besides, it's not the end of the world if the bad guys win every once in a while.
I'm willing to see how this plays out on a live test. If it becomes a problem, we can talk about other solutions then.
