Comment 6 for bug 1374570

Specification updated. <https://wiki.ubuntu.com/AccountPrivileges?action=diff&rev2=20&rev1=19> (This change also included part of the design for bug 1224756.)

The changes step by step:
A. "Other app access" is renamed to "App permissions".
B. Since "App permissions" is no longer "other", "Location" is included in "App permissions".
C. "Location" also remains at the top level of "Security & Privacy", because it's not *just* about app access to location. So you can get to that screen from two places.
