Finish Devalloc miso app prototype

After hours of trying to get a page abstraction working in a Miso app (both
Devalloc and Hero) I had a revelation: Miso is an SPA - *single* page
application - framework, and so trying to put multiple pages into it is
fundamentally at odds with the rest of the architecture.

Of course this is also a problem with Elm's pattern of nesting models in order
to create a page abstraction. They can pull it off because they don't also try
to do isomorphic rendering.

In hindsight this should be obvious... if I actually do want some kind of
page-like abstraction or separation, then I need a much more complex server that
can embed different Miso apps based on some logic. But this is more like
multi-tenancy, or something.

Also I'm starting to think that I don't want Devalloc to be an SPA anyway, so
I'll try an experimental branch where I rip it out and just use Servant, Lucid,
and Turbolinks.
