[FT] Kra'Vak Integral Armor

The current Integral Armor proposal is:

5% mass = Armor 1 (acts as screen-1)
10% mass = Armor 2 (acts as screen-2)
Cost = mass x?

Fiddling with the design system last night I would go for a cost of about MASS
x 6 rating.

The normal shields costs are MASS x 3, but these logical shields can never be
damaged which is a huge advantage.

Filling in the design spreadsheet with a Cost of 3 the points for the KV were
too low, 6 gave a better NPV closer to the magic 1.5.

I filled in all the MT designs, I used average hulls throughout as a baseline
and generally the system worked though there were some anomalies. I find it
difficult to justify a weak hull with Integral Armor anyway, so I plumped for
average like the NAC designs.

I decided on installing all the systems as in MT and varying the mass to
balance. Obviously you could also hold the mass and vary the systems, But I
wanted to preserve that aspect of the MT designs.

As a result some ships had to have a lot more MASS to hold their systems, more
than double their MT counterparts. Others fitted well. Others required a less
mass than expected.

The Thrust point threshold i.e. going from 8 to 6 caused some ships to have
lower mass than the class below them.

I've put the proto full MT design spreadsheet on the web site, but using
'yesterdays' design system.
