Merge transports' nanobots into hull

[JorgeRyan]

Iif you're worried about transport pirates not being able to repair with nanos on the fly, why not remove nano's and buff armour for large transports only? 4-5k ships (or maybe even >3k). They are the most common ones that newbies rush for, to get the maximum haulage. And it means that smaller ships still get to repair themselves.
