Upgrade Meteor.
Update Meteor yet again.
Merged with origin. WIP.
Move to layouts from {{renderRoute}}

This is because iron-router does not support rendering at places other
than the body.
Self close the <hr> tag.
Move to simpler use of 'yield' with iron-router.
Add a simple favicon.
Fix the handling of routes.

The fix was to return an empty array instead of `undefined` from the
publications on the server so that the `ready` function on the client
subscriptions is called. Otherwise, `iron-router` will refuse to
proceed.
Bump meteor version. Again.
