add job chronology back to the mix.  Try to improve error handling on
JSPs.  Change all FK constraints to initially deferred to deal with out
of ordering operations during flush.
All chronology logging now through the method logJobChronlogy on
JobModel.  Sequence chronology using a counter on the job to ensure
ordering.
add current log sequence of a job to the readable view
Fucking job chronology works now.  Well, mostly.  Still double logging
inserts.  Because hard problem.  Anyways, double log on UNSET is
filterable with UNIQUE so it's usable.
