Copying from CHANGELOG.md:
- added support for queuename display for OAR and PBS (SGE already there!)
- overspill feature (aka oversubscribe/overcommitment) for SGE systems
- strict checking cmdline var (will compare reported nr. of jobs against displayed/found jobs)
- id column is now more readable (put in brackets)
- fixed long-standing bug that would report incorrectly the queues of jobs in a node, in some cases
- restored deprecated document file deletion
- huge refactoring of the codebase
