-- In sched/wiki and sched/wiki2 properly support Slurm license consumption

    (job state reported as "Hold" when required licenses are not available).
 -- In sched/wiki2 JobWillRun command, don't return an error code if the job(s)
    can not be started at that time. Just return an error message (from 
    Doug Wightman, CRI).
 -- Fix bug if sched/wiki or sched/wiki2 are configured and no job comment is 
    set.
