I think the scope here needs to be a bit wider - this PR will fix the container issue for live views that are still in preview, but not for live views that are out of preview mode and use the regular live layout, which also indiscriminately wraps its inner block in a container.

The solution that I'm thinking is...:

• Update the live layout so that it no longer wraps its contents in <div class="container">...</div>.
  • (Possibly at this point, we just delete the live layout, because it's not doing anything. In theory, we could keep it, in case we ever decide that we need or want a shared live view layout that's separate from non-live-view pages, but that seems pretty unlikely to me)
• Update the live views that currently use the live layout to wrap themselves in their own <div class="container">...</div>.
  • Commuter Rail and Subway alerts/status pages.
  • Schedule Finder Departures Page
  • Search page
  • Trip Planner
  • Stop Map (Optional - this page is a lo-fi proof-of-concept, but it does look pretty silly stretched all the way across the screen!)
