Route access

[Swader]

Rauth works well for limiting access to classes and methods, but sometimes people will still want to limit access to routes directly.

Find a way to hack around the router's configuration so that route definitions can include the "groups" allowed to access them. Then, in a UI we've yet to build, make possible group-to-route matching. Coupled with Rauth, this will give the end user full and totally granular control over all areas of the app.
