Comment 8 for bug 1361127

Specification updated. <https://wiki.ubuntu.com/SecurityAndPrivacySettings?action=diff&rev2=62&rev1=60>

As Andrea said, by adding the "5 minutes" summary value to the "Lock phone" item, I made the item look as if it was just for the timeout and not for anything else. This was a silly mistake.

Renaming the screen to "Locking and unlocking" also makes progress in reducing the number of times the word "phone" appears in the UI.
