LP 1212456 customize items out display

Control when lost, longoverdue, and claimsreturn'ed items display in the
top vs bottom list in the items out interface.  Also, control when such
circs should be hidden when checked in, regardless of whether the
transaction is still open (from fines, etc.).

ui.circ.items_out.lost
ui.circ.items_out.longoverdue
ui.circ.items_out.claimsreturned

The values for the settings are bit flags.

1 = show in top list
2 = show in bottom list
4 = hide when checked in

The magic numbers for admins to enter are:

1 = top list, then bottom list (if xact is open)
2 = bottom list, then bottom list (if xact is open)
5 = top list, hide when checked in
6 = bottom list, hide when checked in
