A373: Set prisoners and guards route (variant "B")
This sets joint routes for all characters in prisoners_and_guards.
The first half of the list (guards 12,13 and prisoners 1,2,3) are set to the route passed in (A',C). The second half of the list (guards 14,15 and prisoners 4,5,6) are set to route (A'+1,C).
Used by the routines at wake_up, end_of_breakfast, go_to_time_for_bed, set_route_go_to_yard, set_route_go_to_yard_reversed and set_route_go_to_breakfast.
