Change game speed on aggression

[Trickster]

When you are playing on Fast/Fastest, if you are being attacked (Same trigger as the Portrait flashing red) game reset to "Normal" speed.

I can't count the number of time I sent one of my squad mate to the nearest town just for a simple milk run... By the time I notice the red flashing portrait, he's already bleeding out on the floor or too crippled to start fighting back.

Might need some tuning so that, if you put the game back to "Fastest", it doesn't get slowed again from the same squad targeting you.
