Rebased working branch to current master.

Added support for storing a few more settings on the server:

eg.circ.patron.summary.collapse

circ.renew.strict_barcode

The full supported list is now:

eg.circ.checkin.no_precat_alert
eg.circ.checkin.noop
eg.circ.checkin.void_overdues
eg.circ.checkin.auto_print_holds_transits
eg.circ.checkin.clear_expired
eg.circ.checkin.retarget_holds
eg.circ.checkin.retarget_holds_all
eg.circ.checkin.hold_as_transit
eg.circ.checkin.manual_float
circ.checkin.strict_barcode
eg.circ.patron.summary.collapse
circ.bills.receiptonpay

TODO items from previous comment still stand.
