Removing the per-transit type supply routes allows us to find the best
route from A to B even if the unit needs to switch transit modes along
the way.
The "best" route is the one that will generate better gameplay. That is,
convoys are preferred to ships (use cases for GMT are rare in DCS), and
ships are preferred to airlift (reasons to attack cargo ships are also
rare). Avoiding airlift is also a good strategic choice generally since
it consumes aircraft that could be performing other missions.
The extreme weight against airlift in the pathfinding algorithm could
probably be scaled way down so that airlift would be given preference
over a very long trip, possibly only for urgent transfers.
Later when we add rail that will probably be given the most preference,
but possibly between road and shipping.

The simple form of this works, but without the multi-mode routing it'll
only get used when the final destination is a port with a link to a port
with a factory.
These also aren't targetable or simulated yet.

This gives a clean break between the transfer request and the type of
transport allocated to make way for transports that need to switch
types (to support driving to a port, then getting on a ship, to a train,
then back on the road, etc).

Downside to the current implementation is that whether or not transports
that were purchased last turn will be available for airlift this turn is
arbitrary. This is because transfers are created at the same time as
units are delivered, and units are delivered in an arbitrary order per
CP. If the helicopters are delivered before the ground units they'll
have access to the transports, otherwise they'll be refunded. This will
be fixed later when I rework the transfer requests to not require
immediate fulfillment.

Historically this inherited from Event but there was no reason for that.
That's gone now. Finish the separation and move the unit order tracking
class out of the combat results reaction class's file.
