No the BrowserToolbar would have a webView property that points to the current
active webView. That is the only thing it has to know about.
So the only thing that needs to happen when we switch a tab is:
browserToolbar.webView = newWebView
Or probably a bit higher level in our case:
browserToolbar.tab = newTab
Which can take the webView from the Tab.
(Which we probably want since we likely have some extra state attached to our
tabs that is not available solely through the webView.)
And all the controls in it will reflect the current status of the tab switched
to and update nicely when they change.
