LP#1695007 All-circulations slim DB VIEW

Adds a new view action.all_circulation_slim which collects all
action.circulation and action.aged_circulation rows into a single set,
without the added joins for copy and patron data imposed by the existing
action.aged_circulation view.

The new leaner view is now used by various other views and APIs in place
of the all_circulation view:

DB:  action.all_circ_chain()
DB:  action.summarize_all_circ_chain()
DB:  rating.percent_time_circulating()
API: open-ils.circ.retrieve
API: open-ils.circ.copy_checkout_history.retrieve
API: open-ils.circ.copy_details.retrieve
API: open-ils.circ.renewal_chain.retrieve_by_circ[.summary]
API: open-ils.circ.prev_renewal_chain.retrieve_by_circ[.summary]

To Test (webstaff style):

[1] Open a copy in the web staff Item Status / Detail View interface
    that has live and aged circulations.
[2] Open the Recent Circ History tab
[3] Confirm relevent fields for both types of circs display as expected
    and that the Patron field for the aged circulation shows a value of
    <Aged Circulation>
