JoePfeiffer 42022c7815 Closes 443

When the events STAGE_SEPARATION and EJECTION_CHARGE are both triggered by
BURNOUT, both events occur simultaneously and either can be inserted
in EventQueue first.  If STAGE_SEPARATION is inserted first, the
filter in BasicEventSimulationEngine.java ignoring events from
components that are no longer attached to the rocket drops ignores
EJECTION_CHARGE.  If second stage IGNITION is triggered by
EJECTION_CHARGE it is filtered out, and second stage IGNITION fails to
happen.  This can be seen in the following snippet of a log file:

10593          TRACE [pool-4-thread-1] n.s.o.s.RK4SimulationStepper - Thrust = 0.0

Note here that there was no IGNITION in the sustainer branch, and the
Thrust is 0.0 at the end of the snippet.

Moving the test for ignition events ahead of the filter assures the
IGNITION is scheduled, as seen in this log file snippet:

Here, the IGNITION does take place, and Thrust is non-zero.
Displaying a plot of the flight, and saving CSV files, shows a normal
two-stage flight profile.

This commit does two things:

(1) adds a little more logging, in particular logging what event has been
    obtained from EventQueue and logging when that event is ignored.

(2) moves the motor ignition events test ahead of the filter, as
    described above.

Build Status -

Overview

OpenRocket is a free, fully featured model rocket simulator that allows you to design and simulate your rockets before actually building and flying them.

The main features include:

Six-degree-of-freedom flight simulation
Automatic design optimization
Realtime simulated altitude, velocity and acceleration display
Staging and clustering support
Cross-platform (Java-based)
