Add face pool, blacklisting, and action explanations to people admin

Removed faces now go to an "Unidentified pool" cluster rather than
disappearing. Deleting a cluster blacklists all its members so they are
skipped by future re-clustering runs. Pool faces can be assigned to a
named person or individually blacklisted. A plain-English info box on
the detail page explains what each action does and that no photo files
are ever modified.
