Allow the role attribute

Was missing the Google Provided boilerplate code (ga.js).
Analytics module should call track page.

Remove most WDN markup and just use custom JS build.

Add a class when no local search is done.
Remove classes/divs not needed in embed.

It should now be mathematically centered

The local script can now be loaded with requirejs without relying on any
globals!

The google module will only be loaded after google's sheet has been
loaded.

Fixed bad padding alignment.

and fix rendering of site regions

Google search tool appears to be communicating with the search page via
multiple domains. Prevent that communication from triggering searches
with Google data.

Messages posted from the same domain or browser exentions will be
ignored.

When a local search occurs (not triggered by explict tab click),
automatically switch to the "All of UNL" tab if no result are detected.

The v1 API method "execute" needs an object as the third param to avoid
a TypeError.

This allows other objects (namely the Directory controller) to trigger
an interface change.

The Directory controller triggers a UI change when their are no results
for the current filtered view state.
