There were several typos in the unbinding section of FGInterface. This meant

that after a reset or reposition, several FDM variable were not unbound
correctly and left dangling pointing to unallocated memory.  This wasn't
a crash type bug, but those properties then had bogus values.  This
specifically prevented the turn coordinator gyro modeling from working after
a reset or reposition.
