Oops. A last minute change broke piston engines. The "phantom" fuel

Browse source 
tanks created by the C++ code look empty, and were causing the fuel
code to detect out of fuel conditions.  Since there is no way to tell
a "FDM" tank from a "C++" tank, I just filter them by capacity.  Very
ugly hack, we need to fix the code to report only the tanks created
by the aircraft/FDM configuration.
