In preparing the stealth mode switch-over I noticed the announcement bar at the top of the nav could be made more flexible.
Right now it requires it to be a link, but maybe we dont want it to be a link (or dont have a link for it)
It also does not utilize the custom link component so that external links are automatically opened in new tabs.
So modifying that here so intenral links are not opened in new tabs and we can just pass text if we like
