Script should not die if one job is not complete.
Added check for running instance of cron script so that this script will die if another instance is already running.  Also, added code to update job statuses in JobDB based on AWE status.  Need to update mgrast awe template so that mgrast stage names mostly match awe process descriptions.
Edited the mgrast awe template to have process descriptions the same as the mgrast stage names when possible for updating job statuses.
Some edits to update mgrast stage statuses roughly following the AWE process states.
