Update deprecated Google classic/standard auth scope to use Google+ scope

* Change on account here prompted for Google+ profile access and "circles" *(manually changed with the pencil to "only you")*... checks okay.
* Exact deprecation is described at https://developers.google.com/+/api/auth-migration#timetable ... attention point at OpenID deprecation which says to migrate to Google+ signin
* Upgrade reminder to final stage CSS coloring.

Closes #613 and applies to #484
