Fix for dead links in the ornithopter aircraft README and aircraft.dat files.

The link to Assoc. Prof. Michael Selig's website for the UIUC aircraft has shifted to
http://m-selig.ae.illinois.edu/apasim/Aircraft-uiuc.html . Therefore the old dead link has been
replaced with this correct link.

Lockheed1049h version 2.5.3: Fix wrapping bug in Pictorial Deviation Indicator

It was not possible to select radial 359.

Patch by Richard Senior.

Lockheed1049h: Remove artificial boosting of attitude indicator gyro

Removed timer loop that artificially boosted AI spin because the AI
appears to be simulated properly without it. This code may have been
working around an old problem that has gone away.

To maintain accuracy in the AI, the spin must be above 0.8. To maintain
spin above 0.8, the vacuum system must provide a suction above 4.0. At
low RPM it doesn't do so, but once the engines are above idle, the AI
works correctly and decays slowly when engines return to idle.

$FLIGHTGEAR/src/Instrumentation/gyro.cxx.

Lockheed1049h: Improved autopilot controls

Reference: Lockheed Super Constellation Crew Operating Manual, 4-216
http://www.avialogs.com/viewer/avialogs-documentviewer.php?id=3447

* Disable autopilot switch when altitude switch is on
* Disable pitch wheel when altitude switch is on
* Allow bank select in NAV modes, returning to NAV when bank == 0
* Allow bank select up to 30 degrees (produces standard rate turn)
* Make default pitch consistent at 4.0
* Implement autopilot warning light using property rules
* Autopilot considered on if speed hold switched on via keyboard

Lockheed1049h: Autopilot tuning

* Reinstate wind correction using anti-windup logic
* Adjust filters for smoother flight

Patch by Richard Senior.

Lockheed1049h: delete some unused Nasal files.

Lockheed1049h version 2.5.2: Implement RMI needles using property rules

The existing implementation used Nasal scripting to overcome an
issue with the in-range flag which was fixed by commit 56912c17
in Oct 2011.

Filtering in a property rule creates a smoother animation of the
RMI needle when switching stations, during station passage and
when the signal is poor.

Patch from Richard Senior.

JA37: Version 3.021
GUI: Added turn rate to performance monitor.
GUI: Added turn radius to performance monitor.
Sim: Changed structural limit warning to 7 G and -2.66 G. Pilots would normally be operating within this limit.
Sim: Changed structural break limit for wings to 12 G at 33477.19 pounds (normal start weight).
GUI: Added sink rate to monitor.
Aero: Increased rear gears rebound value, to let it better cope with touchdown at 5 m/s sink rate.
Aero: Added stall hysteresis for good measure.
Aero: Decreased initial fuel temperature from 70 to 59 fahrenheit.
Aero: Adjusted wave drag to counter the increased drag from drop tank to reachieve max performance values.
Aero: Lowered static friction on rear gears to help with crosswind landings. Increased front gear friction in turn.
GUI: Added colors to different sections of performance monitor.
Aero: Adjusted the steering limit in regard to ground speed for the new friction values. It now steer significant less.
Model: Added Flightgear livery.
HUD: Set default brightness to brightest.

Citation II: make the pilot and copilot seat armrests move smoothly.
