Fix link for new design doc
Add tests for documents/views-changes

Closes COUCHDB-2282
Link local docs in Fauxton

Instead of linking to the latest version online, we link to the
docs for the locally installed version. The docs are
generated automatically when running make / make install, if you
have Sphinx installed. For development, the dev-server will just
proxy the request.

Upgrade d3 to version 3.4.11
Refactored Layout and View, upgraded to latest LM

The Layout object was a simple wrapper over the Layout constructor
instead of extending the constructor itself.  I've patched this to make
it more consistent and removed duplicative methods.  I've also removed
the tests for `removeView` since that is now a built-in method.

The latest LM contains bugfixes and render performance updates that
unforuntately have to be opt-out.  Areas in the source or tests that are
expecting synchronous renders must be patched to work asynchronously to
take advantage.
Upgrade backbone.layoutmanager

Work off Tim's initial commits and adjust to cater for the use of
establish functions in views and routeObjects.
We don't want to immediately render the view. We first want any pending
promises returned from a routeObjects establish and a view's establish
to complete before rendering the view.
