DebugReplay: split CreateDebugReplay to allow calling with file name instead of args.
test/RunAnalysis: disable Contest incremental mode

Reduce overhead by not doing partial calculations.
ContestManager: UpdateIdle() returns false when disabled
ContestManager: RunContest() returns false for failure

Don't copy an undefined result in ContestManager::UpdateIdle().
FlightStatisticsRenderer: use range-based for
TrailRenderer: move code to Prepare(), DrawPreparedPolyline()
TrailRenderer: DrawTraceVector() requires only Projection instance

Method doesn't use anything WindowProjection specific.
FlightStatisticsRenderer: move code to DrawContestSolution()
FlightStatisticsRenderer: don't draw OLC-Plus result twice

Change the loop to a switch/case statement with explicit instructions
for each contest.

In OLC-Plus, draw only the "classic" and "triangle" result, but not
the "plus" result (which equals the "classic" result).  In OLC-League,
draw the triangle on top of the classic result.
FlightStatisticsRenderer: draw closed contest triangle

Use only index 1..3 for the triangle and draw a closed polygon.
Previously, the triangle was not closed when looking at a partial
result (TRAC #2775).
