Made wx[F]File::Write(wxString) convert string to multibyte encoding

(added optional conversion parameter). If someone actually wants to write
text files in real Unicode format, I feel that a wxMBConvUTF16 or
something should be written (which would be more portable than writing
wchar_t buffers directly, considering byte order and widths and such).
