LP1913811 Items out notice summary API batching

Tweak the open-ils.actor.user.itemsout.notices API to accept an array of
circulation IDs so the call can be batched from the client.  Similarly
modify the AngJS client to request the notice summaries in batch.

Further improves the notices API by removing an unneeded join and a
minor security fix to verify perms based on the in-database user ID
instead of the ID provided by the caller (w/ the note that the API only
returns numbers, not user data).
