Move authentication and redirection out of router and into React components and Redux state

[tomRedox]

See @ffxsam's comment here: ffxsam/ffx-meteor-react-boilerplate#8 (comment).

This probably relates to the separate issue of whether we should be bringing knowledge of the routing into Redux too so that restoring a previous state would then restore the page that goes with that state too.

@Gaereon recommends looking at this article in comments on a github gist here. That example is using JSON Web Tokens (JWTs) (which is an open source standard) and a paid authentication service auth0.

Need to think about how all this would tie into Meteor's existing security structure.

Hey!

This article should prove to be useful.

Hi @ffxsam, much appreciated.

Arunoda links to an interesting discussion on the Meteor Forum in the comments of that article too: https://forums.meteor.com/t/question-to-mdg-building-routing-into-core/4378/37
