Locale: expose NumberOptions to QML

As we want to specify how DoubleValidator and fromLocaleString handle
number separators, we need to expose NumberOptions to QML.

The referenced bug report is still unsolved, as we  we still lack a method
to change DoubleValidator's behavior and NumberOptions does not have a
value to ignore occurrences of separators at arbitray places.
