Feature request: Automatic save comment of class

[plbt5]

When creating a comment, I often forget to explicitly save the comment before hitting the [OK] button that closes the class. Unfortunately, the [OK] button does store modifications that have been made about the class, but does NOT save the comment that was added. Suggestion: Remove the [SAVE] button as part of the comment box, and include its save-method to the Class's OK-method.
