FOOTPRINT_WIZARD_FRAME::ParametersUpdated(): fix a reentering issue 

On wxWidgets 3.0.5, in some cases calling ReCreateParameterList() generates
a EVT_GRID_CMD_CELL_CHANGED that call ParametersUpdated()
and creating an infinite loop
Note also it happens **only for languages using a comma** instead
of a point for floating point separator
It does not happen on wxWidgets 3.1.4
