Fix Quartz 2.2.2 Upgrade Script not working

The Quartz 2.2.2 Upgrade Script referenced in the upgrade instructions is broken. Fix the problem by adding the following line to the script:

alter table qrtz_fired_triggers add column sched_time bigint not null;

Note also that our Quartz installation (originally based on a Nuxeo 5.6 install) required the following additional script changes to bring it current:

alter table qrtz_fired_triggers drop column is_update_data;
alter table qrtz_scheduler_state drop column recoverer;
