Fix '@Sens. ZSensorSens' KeyError loading picoforce 0x07200000 curves.

Regression from 93e0e4284534.  Of course, we still don't know where
the z-data is in the 0x07200000 curves,
  http://code.google.com/p/hooke/issues/detail?id=26#c4
so its hard to know if this is the right sensitivity.  It doesn't
crash anyway...
