Wrap the functionality in a request for Undo Wikipedia Blackout's details in
order to determine whether or not today is a known blackout day for
Wikipedia.

Attempt to hide the overlay before it even appears and ensure the core
known elements are not hidden by the blackout code.

Tell the background page to show the page action now.
