As yet untested proxy vertexes in graph2
Turned down unneeded noise on restoreState for MIMEBeans
Turned up noise on saveState for MIMEBeans with full stack trace in the event that closeMIMEEntities returns false
Set MIMEEntity to auto-close on parent document if it's .recycled() (For legacy implementations)
Document.checkMimeOpen() only reports problems once per document rather than on every Item accessed, so it's possible to trace what's happening.
Document.closeMimeEntities now properly returns a boolean value if there was no entity name specified
Document.recycle closes the MIMEEntities automatically. (For legacy implementations)
