save some startup parameters under /sim/startup/options/. options.cxx puts

them under /sim/presets/ but they aren't save there, and as fgInitPosition
and its subroutines overwrite them, we lose the information about what the
user really wanted. This is a temporary solution -- it really belongs into
options.cxx.
