Add password generation browser UI for Windows.

The mocks that I am modeling this off of are located at http://dev.chromium.org/developers/design-documents/password-generation. You can see a screenshot of this implementation at http://www.corp.google.com/~gcasto/windows_ui.png

There are two major differences between this implementation and the mocks.
 - Currently the bubble does not have a close button, but instead is closed when it loses focus. Doing it the other way requires
   constructing a native close button (which wasn't obvious to me) and controlling when to hide or move the UI (say when you switch          
   tabs or move the browser window).
 - There is no clickable image to regenerate the password. This should be trivial once we have an image to use.

Both of these can be added in a later CL. I also need to add some polish to the bubble (I don't like the font, not sure if I like the spacing, etc).

Note that what I'm doing in the renderer right now is temporary until I get the shadow dom changes into WebKit.
