This very large change does a bunch of things. Primarily, the use of web

components and custom elements has been swapped out for backbone.js. The

reasoning behind this was multifold. First, the way that data gets passed in to

custom elements (via attributes) was a little annoying for building

highly-interactive pages. Second, adding custom elements involved a surprising

amount of boilerplate code, made worse by the fact that some browsers needed

shims for CSS. Finally, the specs for webcomponents are still in quite a bit of

flux, and it's looking like things are going to change significantly in the

next year or so.
This also:

- Tweaks some of the layout to fill the window better (sometimes some pages

  would have @header-height worth of their content hidden at the bottom).

- Adds a REST API for the database using express-restify-mongoose. This is

  extended a bit to add user-based access control. Why restify doesn't include

  that is a mystery to me.

- Adds some new schema for groups and some additional data into user which will

  be used in a future change.

- Adds a cute spinner that shows while content is loading.

- Changed around URLs to use fewer querystring parameters.

Checked all existing behavior. Saw that things worked pretty much as expected.
