Update Qstat for better use with JSON output

[grabear]

The qstat command can now be used in a way so that it creats json output:
qstat -f -F json

This is very useful. It can error though at:

OrthoEvolution/OrthoEvol/Tools/pbs/qstat.py

Line 712 in 86a3953

self.run_qstat(csv_flag=True, sqlite_flag=False)
