Replace home directory list with a dashboard

Summary:
Rough cut that still needs a lot of polish, but replace the directory list with
more of a dashboard type thing:

  - Show "Unbreak Now", triage-in-your-projects, and other stuff that you're
supposed to deal with, then feed.
  - Move tools a click a way behind nav -- this also lets us put more stuff
there and subtools, etc., later.
  - Remove tabs.
  - Merge the category/item editing views.
  - I also added a light blue wash to the side nav, not sure if I like that or
not.

Test Plan:
  - Viewed all elements in empty and nonempty states.
  - Viewed applications, edited items/categories.
