Faster page loads for admin interface (down to ~300ms)

[taoeffect]

Currently the work for the new admin interface (#69) has been merged into the admin branch.

Once useful enhancement is to reduce the total page load by an order of magnitude.

The main culprit is the newly added browserify dependency (#73), which adds a whole bunch of unnecessary javascript. Ideally, we don't want a dist/app.js file at all, just direct coffeescript on-the-fly loading.
