Assembly block functionality overhaul

[Kriby]

I think it'd be cool if assembly blocks were more generally useful. Specifically:

1. Allow production capacity to be used to build torpedoes similar to how fighter construction works
2. Allow production capacity to be used for passive hull repair bonuses
3. Create a new ship menu tab where production capacity can be allocated between these three uses

The ship menu tab would give you feedback on what your production division results in re: hull repair bonuses, torpedo and fighter production slots and production time reductions. Captains and subsystems could be added to give bonuses to each of these primary use cases.

On top of these things, I'd hoped that the assembly blocks could be a more integral part of the production of goods, allowing even mobile ships to retool a portion of their assembly power towards crafting products.

This would also allow for arbitrary stations that could split their production between several goods, so you can start small without a huge investment, but later on also consolidate several different productions into one facility to reduce the CPU strain of a dozen stations doing overly-specialized tasks
