QLocale: Add option to pad numbers with trailing zeroes

EcmaScript mandates that number-to-string functions pad the resulting
strings with zeroes, up to the requested precision. QLocale actually
supports this, under the disguise of the "Alternate" flag, used by
QString::asprintf().

We split this flag into the three options it actually represents and
make IncludeTrailingZeroesAfterDot available as a NumberOption. This
allows us to generate numbers in an EcmaScript compliant way.

In addition, a symmetrical option to reject trailing zeroes when
parsing strings to numbers is added.

[ChangeLog][QtCore][QLocale] Additional flags in QLocale::NumberOption
allow generating strings from doubles in accordance to EcmaScript's
Number.toPrecision(n).
