[CLOSED PR] Merge Engineer and Mechanic access

[BatElite]

I should have stated this in an earlier thread, but I think both jobs should have access to the ruckingenur side of mechlab. Construction kinda sucks since you either don't have easy access to building mats (mechanics) or the ability to fill those rooms you can build with functioning equipment (engineers). Leave the engine/solars to engineering and packet/mechcomp nerdery to mechanics. That would primarily require mapping changes though. I'm not sure how feasible that is.

Question: what would both these jobs' "lanes" be if this gets merged? Having access to somewhere implies you're justified doing work there.
