I'm breaking up my local mega patch to land in several chunks. This is
the Blink portion that's needed to build blink_tests successfully with
WebLocalFrame subclassing WebFrame.

Overall, the changes are pretty straightforward. One method changed back
to taking a WebFrame*. It's not yet clear how we're going to coordinate
frame detach for remote frames. Once there's a clear story, I'll update
it appropriately.

The typedef remains for now, as I work on landing the Chrome bits that
depend on this.
