big change to get metadata working fully in DB and on Filesystem, and recover from most common scenarios, improved GUI as well for allowing an immediate search after adding refimg as well

-	* keep overrides across 'deletes/rescans'
-		[DONE] - when we delete/force a full scan then move overrides into disconnected* tables
-		[PARTIAL] - when an individual face is deleted - need to keep any associated override
-				code is [DONE]
-				TEST! (no way to force a delete via gui as yet)
-		- when we scan a new face, we need to see if there is a matching override, if so, add override back & delete disc*
-		- TEST (add an override, delete refimg, re-add refimg & re-scan)
-		- TEST (forcescan job)
