Color by performance tasks adjusted (based now on ru_utime, not ru_wallclock).
context meny Update from Database fixed (we now copy entire input from qacct).
read_qacct can currently read info about single task, not entire job.
Log script adjusted again. It currently tries to retreive data from qacct, and on fail falls back to qstat. There is a gap between these two sources causing particular tasks to disapear, which is bad thing.
