Can this file be consolidated with get_auth_frame into something just like
signin_utils ? Does that make sense?

Done. Code-wise this makes a lot of sense, I just had to edit a bunch of
#includes.

+// Gets the browser containing the web UI; if none is found, returns the last
+// active browser for web UI's profile.
+Browser* GetDesktopBrowser(content::WebUI* web_ui);
