Initial draft with UI changes

@gwprice and @mhoeber , this still needs changes to policy key settings/new images for the Studio changes that will be in tomorrow's release. Also, most of the paragraphs are not wrapped onto new lines, but I didn't want to distract from where I actually made changes. I'll do that later.
Elsewhere, you have use "Discussion list" to refer to the list of threads rather than the list of topics.
