More variant fixes.

Citation II: correct some paths

include="" requires relative paths to avoid errors in fgrun (in
contrast to <model><path>).

Use the human models in the Citation directory instead of those in
$FG_ROOT/Aircraft/Generic.

Citation II:

* Adjusted seats height

MiG-15 3.0.9: regression fix: make elevator and rudder move again

The regression was introduced by the new FDM in 3.0.8; the properties
/surface-positions/{elevator,rudder}-pos-norm were fixed at zero, so
the surfaces no longer moved. This change fixes that.

* MiG-15bis.xml (fcs/pitch-trim-sum-clipped-scaled): rename to
fcs/elevator-pos-norm.
(fcs/rudder-trim-sum-scaled): rename to fcs/rudder-pos-norm.
(fcs/rudder-pos-deg_1, fcs/rudder-pos-rad_1): remove "_1" suffix.

Adding Instruments. Increased Rembrandt compatibility. Update for FG 3.x
