[MSVCRT] Implement wcsftime

[Lionel Ulmer]

This is a partial implementation of 'wcsftime'. What I mean by 'partial' is
that if the format string contains any Unicode chars, it won't work. There
is the same problem if any of the %... tokens returns an Unicode string.

Anyway, for the application I am playing with, it's enough :-)

Changelog:
  Start implementing wcsftime
