[WIP] IRAI (Intelligent Random AI)

That sound really good TDW!

- speed restrictions based on crew ability removed. Now just a calculated speed restriction based on damage to the ship is used (no more outrunning the escort - only if it's badly damaged will you be able to do this)

I'm especially happy about this one

Also curious to see how are the DD's acting when firing underwater sub, how many minutes they shoot the area or do they stop when you are out of their trigger area.
