Fixed compilation of wxVector<T> with VC6:

* reverted VC6 hack in wxIf<>, using helper struct instead of typedef
  didn't fix compilation, only caused the compiler to crash instead
  of emitting semi-useful errors
* changed wxVector to use typedef for Ops class instead of privately
  deriving from wxIf<...>::value; this is enough to make VC6 happy
