Enable "Link to Publisher" for a given Trusted Publisher tab

[miketheman]

When navigating to the different horizontal tabs for a given publisher, it's useful to be able to share the URL with someone else. Currently there's no way to share a URL that will open on the specific publisher.

One idea is to update the JavaScript to change the URL when the tab changes, similar to how the project_tabs_controller does it, and thus be able to share the URL and have it activate the selected publisher tab.
