Links many map-specific details such as the station name, z-level information, and allowed jobs from global vars to map datum vars, which should help us maintain multiple maps at once in the future, which will be needed for the future Southern Cross.
Note that a config change will be needed to change GENERATE_ASTEROID to GENERATE_MAP, otherwise no changes should be required to continue normal map usage.
To change to a different map, it's suggested to tick the file that ticks all the other needed files, which for the Northern Star is called northern_star.dm.
-Adds a Polaris version of APC rebooting
-Changes the random APC-bluescreening event to be more sensible in what it does and how to repair it. Bluescreened APCs are permanently unlocked, and can be fixed by removing the power cell and applying a multitool.
-EMP'd APCs now give Bay's timed (or manual) reboot nanoUI so that important places aren't shut off permanently if engineering can't get around to them.
-Nins and twizs no longer **** up APCs when they drain power from the cell completely. Also, drained power comes from the powernet primarily, and only draws from the battery if the powernet doesn't give enough (random chance) or if the cable is cut.
-Bluescreened APC sprite now switches to an open wire panel sprite if a screwdriver is applied.
-Grid checks put a nanoUI notice on APCs. As it is now, you have to wait for the grid check to end or use the grid checker in engineering before you can manipulate APCs.
-Grammar fixes
-More grammar fixes
-My god the grammar fixes
-to_chat'd the user <<s again.
-Merged a small clean-up to power states.
-Bashing APCs to pieces was always ineffective but would spam everyone anyway. Now, it only spams the person bashing the APC. This is a placeholder, ideally you should be able to bash a working APC's cover off if you want its battery out but this PR is already big enough as is.
