Estimate TOTs for packages.

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.
