SMES Coil Cost
- Supply point cost doubled to 150 according to feedback.
SMES Board design fix
- Fixes SMES circuit board issue
SMES Construction rework
- Buildable SMES is now subtype of regular SMES.
- Buildable SMES related stuff moved to separate file (smes_construction.dm)

Please note that this commit is one of two commits which have to be applied together. Otherwise, compilation error occurs. (Code + Map. This one is Code)
SMES Construction rework
- Updates engineering SMES to be of /buildable subtype. (Second commit, rest of the changes in previous one)
Breaker Box AI interaction fix
- AI can now properly interact with Breaker Box, without interacting BOTH as AI and human.
Breaker Box Fix
- Removes source of runtime errors. From my examination of code, it seems these errors happen when breaker box is turned off for the first time. It should work then.
- Mostly temporary fix, i intend to rework the powernet code over time. I would welcome cooperation with @mwerezak as he is currently doing lots of related things.
PARTIAL IMPLEMENTATION - Charged SMES deconstruction & SMES code cleanup
- Cleanup of SMES attackby() code
- Buildable SMESs now have option to override safety circuit by using multitool while the hatch is open.
- Disabling safeties lets you disassemble SMES even if it's charged above 1%.
- If charge is above 5% stored energy may discharge violently. This is percentage based (more energy = higher chance of this occuring + more severe consequences)
- Larger discharges affect whole powernet, burning out some lights and even completely destroying APCs!
- Substation PSUs act as surge protection. Thus, if set up properly damage is limited to few areas which are directly on the main grid (= maintenance mostly)
- STILL NEEDS TESTING. Pushing so other people can review the code and give further suggestions. And because i need to access it on second computer.
Attempt to resolve merge conflict. I hope i won't break something.
