* Nasal/MiG-15bis.nas (altimeter lamp): remove, not used anywhere
(realelectric): replace repeated calls to settimer() with a single
call to maketimer().
(flaps lamp): remove.
* Models/Instruments/MiG-15bis-Flapslamp.xml: use
surface-positions/flaps-pos-norm and other properties directly instead
of instrumentation/flaps-lamp/lamp-ligth-norm (sic).
* Models/Instruments/MiG-15bis-Flapslamp.ac: remove emission from the
Plate.001 material so that the lamp is unlit by default.
