you should put this in namespace 'webkit' - 'WebKit' is supposed to be for
things in the WebKit repository, 'webkit' is the things we implement in chromium
to support our embedding.  this means you'll have to write WebKit:: in front of
some of the types below, but there aren't all that many and it looks like some
of these types already have WebKit:: in front of them

Done.
