Code review comment for lp:~rharding/juju-gui/browser_links

*** Submitted:

Support linking through router code for urls.

- Add state tracking to the subapp and use that to determine which UX
parts
need calling and which do not.
- Add an event to the subapp and views to handle catching requests to
route to
a new url.
- Add tests to walk the paths of rendering to make sure we're updating
and
calling correctly.
- Add some stubs for search, but it's to be implemented in follow up.
