Igonre closure classes when looking for duplication.

I think this is not the right fix, imagine the case:
library1.dart has
typedef void callBackType(int param1, int param2);
and
library2.dart has
typedef int callBackType();

now we import these two into an app as
import library1.dart
import library2.dart
then we should get a duplicate definition error.

With this change I think we won't get an error.

Thanks a lot, Siva.  Sounds like you're right.  I'll investigate if you don't
mind.

Anton, see the updates done in issue 187. Regis and I were discussing this and
we concluded that the implicit signature classes were being added at the wrong
place.
