This used to be horizontal and you changed it to vertical.  Was that
intentional?  (if it wasn't you might want to try a HorizontalScrollView)

Also, do you have any idea why we can't have the layout files in the same
location?

My bad... Fixed now. Also changed gravity as well, and moved it under ui/. It's
part of UI component resources, so I think it makes more sense to move it there.

By the way, I realized that landscape/portrait is determined at the dialog
launch time, and assigned resources cannot change on orientation change once
it's shown. I've filed a separate bug (Bug 418835) so that it can be fixed with
a separate release schedule.
