[fix bug 1106305] Specify What's New Variant For 35 Beta

Users updating to Firefox 35 Beta (due to update Thursday) will see the search /whatsnew page with the following conditions:

* Always see the "forced" door-hanger with "Try it now" if their current default is Google.
* Always see the 'independence' page variation with "Search. Freely" in the title when the door-hanger is shown.
Comments have the wrong version here and below...right? Not a blocker, just clarifying for my own sanity.
