cleanups to pqDoubleLineEdit
requested to merge utkarsh.ayachit/paraview:18518-scientific-notation-in-numeric-fields into release
Make pqDoubleLineEdit not use a format specific double validator. pqDoubleLineEdit should always accept any valid double string. It should only change how it's shown based on the chosen format.
Now, pqDoubleLineEdit also doesn't attempt to cleanup a number entered
by the user. Thus, if user enter 1e10
for the full precision text, the
full precision text stays as so.
Changed default precision used by the widget to mixed rather than fixed.
