- client: scheduling tweak. 

Old: if a project has RR sim deadline misses,
			select jobs to run high-priority on the basis of:
			1) deadline (earliest first)
			2) estimated time to completion (least first)
			This ignores whether jobs missed their deadline in RR sim,
			so it may choose to run a job that's actually in no
			danger of missing its deadline over one that is.
		New: choose only jobs that miss their deadline in RR sim
