Lockheed1049h 2.10.5: minor improvements

* Hide the new taxi and landing light spots from the preview in fgrun:
- Models/light_[crl].xml: new, include <nopreview/>.
- Models/Lockheed1049h_Lights.xml: use them.
* Systems/Lockheed1049h-keyboard.xml: when switching views, use
view.indexof() instead of hardcoded view names for future-proofness.

Updated FDM config files; minor model fixes; AP documentation update

Lockheed1049h 2.10.4: new taxi and landing lights

These new lights replace the lone taxi light cone and actually light
up the runway even without Rembrandt. They are disabled when
Rembrandt is enabled.

* Models/mesh_lights.ac (Cone-texture),
Models/light-cone.eff,
Models/Lockheed1049h_Lights.xml (Cone-texture): delete.

* Dialogs/Lockheed1049h-menu.xml ("hide light cones"),
Nasal/Lockheed1049h.nas (hide-light-cones): delete.
Lockheed1049h-common.xml (hide-light-cones): delete.

* Models/Lockheed1049h_Lights.xml
({Taxi,Left Landing,Right Landing} Light Spot): new.
* Models/light_[clr].ac,
Models/light_spot.png: new; thanks to John Williams for providing them
from his 757-200 model.

Fixed upside down autofeather lights.

Lockheed1049h: fix a typo.

Lockheed1049h 2.10.3: minor improvements to autopilot and ground handling

* autopilot: hold indicated altitude, not absolute altitude.
* FDM: increase the static and dynamic friction of the nose gear to
improve steering on the ground.
* FDM: restrict nose gear steering to 58.5 degrees when the pushback
truck is not connected, 70 degrees when connected (in reality it was
possible to disconnect the steering and rotate the nose gear 90
degrees by hand, but the shared model for the pushback truck allows
only a hardcoded 70 degrees).

Fixed another cabin light bug in Rembrandt.

Partially fixed some bugs of lighting in Rembrandt.

MiG-15 version 3.1.4: crash detection: bugfixes
* make crash messages appear only once every 0.5 seconds
* enabling crash detection after replay
* increase delay time for crash detection after replay

Citation II: wing-flex (first part)
* added filter calculations

ToDo:
* Cut the wings and clip the animations onto the parts
