created_by and creation_date are undefined properties

[matuskalas]

The very useful properties WebProtégé adds, are http://www.geneontology.org/formats/oboInOwl#created_by and http://www.geneontology.org/formats/oboInOwl#creation_date.

BUG: Those properties don't exist in http://www.geneontology.org/formats/oboInOwl, so other properties should be used instead.

MISSING FEATURE: These properties are added automatically by WebProtégé, which is super nice, but only within the "Auto-generated OBO Style Id" option for new entities. It would be super nice to have it as an option irrespective of the ID generation style.

MISSING FEATURE: It would be super awesome to add an option for recording http://www.geneontology.org/formats/oboInOwl#savedBy (which exists in the given namespace), too. Also when an entity is edited.

Million thanks in advance for looking at this (especially the BUG part) 🙏🏽
