[1.1.6] Menu simulation world bugs

[Umbreon]

These bugs are in the simulation maps, not the simulation itself.
Some of these are not visible without super wide/tall monitors.
All of these are minor issues.

menu-simulation-lab has a belt flipped the wrong way round

menu-simulation-artillery has a turret that never gets filled

menu-simulation-big-defence has a roboport that never allows robots in

menu-simulation-nuclear-power has a uranium fuel cell constructor that never gets iron

[Klonan]

Its charming spaghetti rather than a perfect factory
