Record computers to modular computers (#7797)

Things this does:

    Refactors _app_preset_name to use a type name instead. This makes it validate the presets at compile time, making it much more secure.
    Removes all records computers from the code, along with the CMC.
    Replaces all records computers with appropriate modular computers
    Each head of staff now has 1 departmental computer, 1 head-specific computer, 1 head laptop
    Removes the C&C program from the heads that had it, because you're supposed to use the bridge for it.
