Add flags to omit/reject padding in scientific notation exponents
The EcmaScript format for printing doubles in exponent form differs
from Qt's format only in this aspect. EcmaScript explicitly prohibits
leading zeroes in exponents. It is thus worthwhile to add those flags
in order to be able to generate and parse doubles in compliance with
EcmaScript.
[ChangeLog][QtCore][QLocale] Additional flags in QLocale::NumberOption
allow generating and parsing doubles in EcmaScript compliant format.
