This Pull Request lets users plan Tanker flights.
Features:
- Introduction of `Refueling` flight type.
- Tankers can be purchased at airbases and carriers.
- Tankers get planned by AI.
- Tankers are planned from airbases and at aircraft carriers.
- Tankers aim to be at high, fast, and 70 miles from the nearest threat.
(A10s won't be able to tank)
- Tankers racetrack orbit for one hour.
- Optional Tickbox to enable legacy tankers.
- S-3B Tanker added to factions.
- KC-130 MPRS added to factions.
- Kneeboard shows planned tankers, their tacans, and radios.
Limitations:
- AI doesn't know whether to plan probe and drogue or boom refueling
tankers.
- User can't choose tanker speed. Heavily loaded aircraft may have
trouble.
- User can't choose tanker altitude. A-10s will not make it to high
altitude.
Problems:
- Tanker callsigns do not increment, see attached image. (Investigated:
Need to use `FlyingType.callsign_dict`, instead of just
`FlyingType.callsign`. This seems like it might be significant work
to do.).
- Having a flight of two or more tankers only spawns one tanker.
- Let me know if you have a solution, or feel free to commit one.

The AI purchaser will aim to have a 50/50 ground/air investment mix.
This allows it to overspend on one category if significant losses were
taken the previous turn.
The total purchase amount is still limited, so if the bases are full
when only 10% of the investment is in ground units, the full budget for
the turn will still go to air.
The usual symptom here was the game breaking when a carrier is
destroyed. The carrier would no longer be operational but missions would
be assigned there that could not generate flight plans.
Unit composition is defined by the doctrine. The most understaffed CP
will now get the most underrepresented unit type. Previously a random
understaffed CP would get a random unit type.

This limit is determined by the number of buildings that belong to Ammo
Depots at the front line's connected Control Point. The limit increases
for every surviving building at ammo depot objectives.
There is a lower limit to the number of units that will spawn, so that
if there are no surviving ammo depot buildings at a control point, there
will still be some ground conflict.
Target the air defenses whose *threat ranges* come closest to friendly
bases rather than the closest sites themselves. In other words, the
SA-10 that is 5 miles behind the SA-6 will now be the priority.
This also treats EWRs a bit differently. If they are not protected by a
SAM their detection range will be used for determining their "threat"
range. Otherwise a heuristic is used to determine whether or not they
can be safely attacked without encroaching on the covering SAM.
DMS with decimal seconds is what the hornet uses for PP targest. In the
future we'll want to make this aircraft specific (and potentially user
preference for jets like the A-10 that can handle both L/L and MGRS).
We don't need to include a SEAD flight in missions against EWRs or SAMs
that no longer have a radar.
Also plan DEAD missions against air defenses that have no radars.
Previously we would never finish killing launcher only sites (which
cannot defend any more, but are cheaper to return to working order than
a fully destroyed site) nor would we plan DEAD against IR SAMs or AAA.
We were setting up all the correct *target* waypoints but the AI doesn't
use the target waypoints; they use the targets property of the ingress
waypoint. This meant that the flight plan looked correct in the UI and
was correct for players but the tasks were set up incorrectly for the AI
because building TGOs are aggravatingly multiple TGOs with the same name
in the implementation.
Mission targets now enumerate their own strike targets so that this
mistake is harder to make in the future.
This won't be perfect, the AI is still not able to parallelize tasks and
since buildings aren't groups they can only attack one structure at a
time, but they'll now at least switch to the next target after hitting
the first one.
As a bonus, stop bombing the dead buildings.

This really needs to be a proper type, but this is a start: create new
categories for the types of TGOs that are missing. This removes some
icon special cases.
