Decrease the OT simulation cooldown

# Explain why it's good for the game

Increase how fast an OT can test their different chems, specially after
the OT nerf people want to test new recipes for the m15s, rockets ,
shells and 2 minutes is too long for that.

40 minutes for 20 tests before.
20 minutes for 20 tests now.
