extend wxXLocale with wxStrto[d,l,ul] functions; make wxXLocale::Init() a little bit smarter on Unix systems; make XLocaleTestCase not fail on systems where french/italian support is not installed

Conversely, if a program wanted to output the number in French locale, even if
the current locale is different, it could use wxXLocale(wxLANGUAGE_FRENCH).

@c wxUSE_XLOCALE was set to 0 during the library compilation.
@section xlocale_func Locale-dependent functions
Currently the following @c _l-functions are available:
- Character classification functions:
@c wxIsxxx_l(), e.g. @c wxIsalpha_l(), @c wxIslower_l() and all the others.
- Character transformation functions:
@c wxTolower_l() and @c wxToupper_l()
We hope to provide many more functions (covering numbers, time and formatted
IO) in the near future.
