[FT] DCP costs

I'm still kicking around ideas for methods of varying ship quality.  One
method is by improving DCPs.  I see two routes to this--either simply
giving more DCPs, or letting players buy upgrades.

If players can buy more DCPs, what should the costs be under the FB
system?  And where on the hull-box track should they go?

Upgraded DCPs would include Enhanced (1 DCP-E repairs system on a 5+,
but two DCPs still only gives you a 4+) and Superior (1 DCP-S repairs
systems on a 4+, no benefit from combining with other DCPs).  What would
the costs be?  Would all DCP's on a ship be the same grade?   Perhaps
you'd also have Green (or Klutz) DCPs?

It would be interesting, in a small campaign with an umpire, to have
secret quality ratings for the DCPs.
