This commit contains a lot of changes. Here are the main ones:

- BWI integration is now available
- The rooms page now sorts by time, not by room.
- Events now show a date
- A debug console is available, using the same page reload shortcut as before
- Updated README
- Events can now include full HTML content the way news items can. The backend doesn't support this yet, but will when a data source becomes available.
- There's a clock on the cover (and every screen) now
- Lots of minor CSS changes
