Semi-restyle some json

Just a start on restyling some .jsons, styling "type" and sometimes "id", but leaving the rest untouched.

I left it conflicting with vehicle_parts.json in master, to show that conflicts can be suitably resolved this way.

The ones with "id" restyled have an unrestyled "name" field just after them, so the joining point should be unique for each entry, leading to sane merges when the rest is restyled.
