For your consideration: T8 updates

[Celludriel]

• Random spawncontainer for fast creating a container of unit types
• Teleporting groups to their currentWaypoint after they are spawned for all patrol scripts
• Possible bug fix where groups would switch to LINE formation on changing waypoints
• Possible to force formation for all patrol scripts

I've tested all tasks and didn't see anything dealbreaking. Feel free to run your own tests as well.
