Dan Albert b5e5a3b2da Plan waypoint TOTs.
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.
