[PATCH 3/5] widl: Write public typedefs into the typelib if they are referenced directly.

[Zebediah Figura]

I.e. write "apple_t" into the typelib given the following snippet:

typedef [public] struct { ... } apple_t;
library {
interface IFoo {
    HRESULT a(apple_t arg);
}
}

Based on a patch by Richard Pospesel.
