Summary:
When we access `/conpherence/view/2/` on the desktop, load the thread on the initial response and ajax in the thread list. Basically, the idea is:
- When we load the thread list, an individual thread, or the widget panel, we send back the piece the user asked for in the response.
- On mobile, we stop there: we don't ajax in anything else, and just hide the other parts of the layout.
- On Desktop, we fill out the other layout components via Ajax.

Test Plan: Hit `/conpherence/view/2/`, got a full page.
