Introduce QDoubleValidator::fixup()
The provided implementation tries to fix positions for the group
separator.
In case of scientific notation it can also converts the value to
normalized form.
It uses QLocale::FloatingPointShortest internally to convert the
double value back to string, so the number of decimals may change
after calling this method.
