Add support for unsigned long long to wxNumberFormatter

Browse Source 
This is necessary in order to deal with the numbers greater than
wxINT64_MAX that can't be represented in just long long.

It also allows to implement the intuitive handling of minus sign for the
unsigned numbers, i.e. not to accept it in FromString(), unlike the
standard functions which do (and parse -1 as 0xffff...fff).

Also extend the tests to check for more boundary cases.

success they return @true and store the result at the location pointed

Note that the overload taking unsigned long long value is only
available since wxWidgets 3.1.5. Also, unlike wxString::ToULongLong()
and the standard functions such as @c strtoul(), this overload does
@em not accept, i.e. returns @false, for the strings starting with the
minus sign.
