v0.3.1

Fixed

• Thrust warnings are printed in the briefing. The estimator's warnings only appeared in
  its structured notes, so whether a pilot saw them depended on the model relaying them. In the
  v0.3.0 live test it didn't, for a Denver estimate that was flagged as suspect. The TAKEOFF
  THRUST line now ends with them, most serious first, for example:
  set N1 0.880 x full-thrust N1 (range 0.825-0.934) — SUSPECT: thrust reduction over the 25% FAA AC 25-13 limit; high altitude (5,511 ft): engine behavior extrapolated, wider range.
  The thrust result also gains a warnings list. Informational notes stay out of the line,
  and N1 values are unchanged.
