[PATCH v2] ieframe: implement COM aggregation in WebBrowser

[Damjan Jovanovic]

Wine's WebBrowser currently just ignores the "outer" it is passed.
Support COM aggregation like Windows does instead.

Try 2 renames the internal IUnknown functions, uses the
hlink_frame to store the outer, and beefs up the unit tests.
