08848a284b Separated some functionality out into reusable classes, and built a
simplistic, text-field oriented interface for major property groups.

The JAR is now executable, so the program can be launched with

  java -jar fgfsclient.jar <host> <port>

bc179de4bd Patch from Jim Wilson:
This is a small patch that makes the autopilot work much better with big heavy
airliners as well as the small Cessnas.  Of course this doesn't address the
way autopilots should be modeled.

But by making a couple changes the "George" is now capable of landing either a
C172 or a 747 very close to the center line of the runway with a moderate
cross breeze (15-20kt).

The changes:
- Added turn configurability so that things like Max Aileron and Roll can be
configured per aircraft.
- Enhanced localizer routine (NAV mode) to begin lining up the aircraft as soon
as the cone is entered.  The former model is adopted for the last 5km of the
approach in order to ensure greater precision (makes a very slight difference).

[float cast added by David Megginson to keep G++ 3.0 happy]

d982efc4c4 Fix two problems:
1. Typo where /environment/density-inhg instead of
   /environment/density-slugft3 was flagged as archivable.

2. Density should no longer be archivable anyway, since it is
   calculated internally and not directly settable by the user.

2852f27bdc Uninitialized data problem. As it turns out, this never bit us because
the _chord member is only used uninitialized in circumstances where the
result is thrown away.  Still, bad practice.  Found with valgrind.

04e083083d Need to call recalc() on the RigidBody during solution, or else it
won't apply the right gross weight due to fuel differences.

When solving for zero force, do so in the global frame, not the
aircraft's.  In principle, this shouldn't matter (zero is zero in all
frames), but in practice this should help to avoid oscillations.
Calculating lift as force perpendicular to the ground (and not the
wing plane) is clearly the Right Thing, anyway.

Also added support for a /yasim/gross-weight-lbs property, which
should be generically useful.

713920356b Property name typo. This resulted in all temperatures being 273K,
which is far too warm at altitude.  Thus, air density (and aircraft
performance) was too low for a given altitude.

7e63c0f6e8 Modify solution heuristics. Do the cruise AoA and tail incidence only
when the lift/drag are really solid.  And defer the approach trim until
the all four of the other variables are perfect.  I believe this should
fix the solution failures under gcc 2.95.2.

040c508aa8 We don't handle propellers turning backwards. This got clamped
implicitly in PropEngine by disallowing negative torques, but that was
removed at some point.  We really need the explosion protection here

8ae364a220 Jim Wilson:
This is a small fix for what turned out to be a major bug.  Ground elevation
was calculated incorrectly when distant from one of the view locations. This
resulted in several problems including bizarre gear trimming, mid air
"crashes" (as in thinking we hit the ground) and so on when close to or on the
ground.

Unfortunately it does require a second ssg traversal when in tower view
(only), but the increased load isn't all that noticable.  For the time being
this really is the best solution.  In a future update I will be eliminating
the unecessary per frame traversals for the static views (without having to
maintain multiple ssgRoots).

When we go to multiple FDM instances we will perhaps need to put the ssg
traversal and ground elevation queries for the FDMs into an event timer that
updates the FDMs ground elevation in a round robin fashion (maybe every 1/n
seconds where n is the number of FDM instances running).
