Organic & Crystal vehicle differences?

[Raapys]

Personally I think that stuff should work like 3 exclusively different 'ways'; i.e. someone's organic, someone's crystal'ish, and others are good old metal.

At least with Kwok's mod, the races with these traits stop building normal ships, armor and weapons when they research their traits anyway, so why not just make them start with it but not have access to the 'metal' technology theme.
