Sketcher: Solver Advanced Control: New Param: QR Pivot Threshold

Browse Source 
================================================================

A new parameter added to the form in order to control how low a value should be
to be considered zero (how high a value shall be to be accounted for in rank calculation)

Debug for QR pivot threshold is also added.
