Add status script

[grzanka]

Users may not be familiar with scheduler commands which check job status.
Along with submit.sh there should be a script status.sh which should query batch system for job status.

It should print sth like that:

Status report
Job array: RUNNING
Submitted on: XXX

First job (no XX) started running at: XXXX

Job 1: PENDING
Job 2: RUNNING (started at XXX)
Job 3: DONE (started at XXX, finished at XXX)
...
Job 100: FAILED
