fix typo in slurm cancel state

slurm calls it CANCELLED not CANCELED
use sacct if scontrol couldnt find the job

when a job has been in COMPLETED state for longer than a certain ammount of time,
slurm does not display it in the output of scontrol anymore. Instead it complains:
    slurm_load_jobs error: Invalid job id specified

When this happens, fallback to using sacct which has access to the full history.
updated changelog

add config option for shell prompt regex

~/.saga.cfg now accepts:

[saga.utils.pty]
prompt_pattern      = [\$#%>\]]\s*$

This hopefully advances #340
Differentiate between DONE and FAILED.
