Engine cleanup

[mugling]

Some initial cleanup to keep down line count of a big reworking of vehicle engines that will follow.

First two commits are migrations and linting. Third deprecates the useless plasma engine and the associated hydrogen tank. Once we have generic engine fuels via JSON we can add some more interesting alternatives then.

Why can't you make the plasma engine useful instead of dropping it?

[Coolthulhu]

Because it uses a very rare resource that everyone wants for diamond weapons.
It's a money-fueled furnace.

That is unlikely to work, as plasma is a solid.

[mugling]

Lets go with none then. The odds of anyone having plasma in a tank are defacto zero given how exceedingly rare it is and the other uses being much more valuable (plasma weapons and cvd machines)

It's entirely non salvageable in it's current form. Once we have generic fuel we can add lots more novel items

Proper steam boilers? Stirling engines? Wind-up mechanics? Wind power? :P
