0.8.7 with flying colors!

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
