Crowded modifier 😄 (#3023)

## Description:

To increase variety a bit more I present: The "crowded" public game
modifier :)
It basically simulates a crazy youtuber lobby. Cramp a lot of players on
a small map 😄
I think its fun, exciting and you actually need skill to manage the
chaos.
5% of public games get this modifier, but because we remove the modifier
for big maps its more like 2.5% (should be something special)
