FlightGear - Flight Simulator FGAddon

Minor changes (cold start eg) and GPK big error (thanks to OO-BRE to call attention to that)

J3Cub: do not pollute the property trees of remote aircraft over multiplayer.

find Models/ -name '*.xml' -exec sed -r -i 's,>/,>,g' {} \;

J3Cub: fix the animations of the beacon and strobe over multiplayer
(Nasal runtime error). Continuation of r3314.

J3Cub: bug fixes in the nasal executed when a remote J3Cub appears in multiplayer.

The entire multiplayer protocol should be overhauled, taking advantage of boolean
properties in fgfs >= 2017.2. Also the J3Cub pollutes the property trees of all
remote aircraft due to numerous and incorrect uses of
<property>/absolute/path/to/property</property> in animations.

J3Cub: bug fix: send the full path to the model file in /sim/model/path.
This makes it possible to see a remote Cub over multiplayer.

Citation II version 4.1.1: bug fix: allow autothrottle to put the throttle to idle if necessary.
(This is a continuation of r3198 aka version 3.5.0; bug introduced in r3155 aka version 3.4.0).

SPU-7, fuse panel and R-826 improvements (model/texture only)
