This removes both the double load that happens on startup and also
makes it possible to get the UI to create a new game if the existing
default.liberation is not compatible.
Previously we were trying to make every potential flight plan look
just like a strike mission's flight plan. This led to a lot of special
case behavior in several places that was causing us to misplan TOTs.
I've reorganized this such that there's now an explicit `FlightPlan`
class, and any specialized behavior is handled by the subclasses.
I've also taken the opportunity to alter the behavior of CAS and
front-line CAP missions. These no longer involve the usual formation
waypoints. Instead the CAP will aim to be on station at the time that
the CAS mission reaches its ingress point, and leave at its egress
time. Both flights fly directly to the point with a start time
configured for a rendezvous.
It might be worth adding hold points back to every flight plan just to
ensure that non-formation flights don't end up with a very low speed
enroute to the target if they perform ground ops quicker than
expected.
Capturing bases is sometimes really annoying because of the DCS unit
AI and our non-optimal ground victory heuristics. Add a cheat option
to allow the player to move on without the tedium.
We were only getting BARCAP results right in BARCAP packages. This
fixes calculations of TOTs and start times for BARCAPs in strike
packages.
The probably needs some refactoring. BARCAP is just the symptomatic
example at the moment, but the real problem is that different mission
profiles exist and we currently only handle one. Making profiles
explicit in mission planning will clean this up, will be needed for
other future mission types, and makes it easier for us to alter
behavior for waypoint and timing decisions based on the aircraft or
mission type.
Stop using "CAP". Use BARCAP or TARCAP instead.
TARCAP no longer allowed anywhere but front lines, since that's all we
have mission planning for right now. Later will add TARCAP and BARCAP
for all objective types with different timing profiles.
Part two of the fix for
https://github.com/Khopa/dcs_liberation/issues/210.
This guarantees that we update the map *after* updating the model that
the map uses to draw flight plans. Without this, after creating a new
game we'd redraw the previous game's flight plans because the model
hadn't been updated by the time the map was.

Weather and exact time of day information is helpful during mission
planning, so generate it at the start of the turn rather than at
takeoff time.
Another advantage aside from planning is that we can now use the wind
information to set carrier headings and takeoff runways appropriately.
Reasonable ground speed depends a lot on altitude, so plumb that
information through to the speed estimator.
Also adds calculations for ground speed based on desired mach. I don't
know if DCS is using the same formulas, but we should at least be
pretty close.
We estimate the longest possible time from mission start to TOT for
all flights in a package and use that to set the TOT (plus any delay
used to stagger flights). This both cuts down on loiter time for
shorter flights and ensures that long flights will make it to the
target in time.
This is also used to compute the start time for the AI, so the
explicit delay option is no longer needed.
Also fixes the CAP racetracks so the AI actually stays on station.
Waypoint TOT assignment happens at mission generation time for the
sake of the UI. It's a bit messy since we have the late-initialized
field in FlightWaypoint, but on the other hand we don't have to reset
every extant waypoint whenever the player adjusts the mission's TOT.
If we want to clean this up a bit more, we could have two distinct
types for waypoints: one for the planning stage and one with the
resolved TOTs. We already do some thing like this with Flight vs
FlightData.
Future improvements:
* Estimate the group's ground speed so we don't need such wide margins
of error.
* Delay takeoff to cut loiter fuel cost.
* Plan mission TOT based on the aircraft in the package and their
travel times to the objective.
* Tune target area time prediction. Flights often don't need to travel
all the way to the target point, and probably won't be doing it
slowly, so the current planning causes a lot of extra time spent in
enemy territory.
* Per-flight TOT offsets from the package to allow a sweep to arrive
before the rest, etc.
Especially considering the button in this position used to be how
players added client slots, confirm that they in fact want to launch
an AI-only mission before launching, and guide them toward the new UI.
