Survivor Number Adjustment

[Sarah_U.]

Summary (a quick, 2-3 sentence summary):
Simply put, adjust the number of survivors depending of the number of aliens at round-start.

Benefits (How this will benefit the server and game as a whole):
It'll increase the chances for people to suffer- Get Survivor, the troubles for aliens rushing survivors and generally increase the survival rate of survivors.
Furthermore, it'll allow for survivors to do more and possibly try to experiment more ideas with the new options they get.

Details (Description of how you think this would work, the benefits, etc):
MINIMUM: 3 survivors, as per currently.
Maximum can be set at your discretion, but obviously having too many survivors can cause troublesome.

Depending of the number of aliens, the survivor role will have its round-start people cap adjusted and have more join up. The base number remains 3 as it've proven to give a relatively fair chance of survival to cunning survivors.

Implementation (Optional, if you have an idea how to implement it):
Set a ratio and implement it to the round-start. Place a minimal value for the number as a failsafe.

Tyler doesn't need to spawn with 2 others. He is robust.

Survivors are already adjusted, and their number varies per game mode.
