[DNM] Substation remap

After discussion with @Zuhayr i decided to remap the substations. Main point of this PR is to remove stuff like cables/pipes under floors, etc. Most substations will be standardised to 2x3 tile rooms. This is a minimum as i need to fit in APC, air alarm, SMES,  breaker, powernet sensor and two entrances.

Screenshots and full info coming soon (1-2hrs from PR creation, not enough time now, sorry)
