v0.0.32

• easier to retrieve and set common message flags such as \Seen, \Answered and $Forwarded
• use MimeMessage.isSeen, .isAnswered, .isForwarded to query the corresponding flags
• use MimeMessage.hasAttachments() or MimeMessage.hasAttachmentsOrInlineNonTextualParts() to determine if the message contains attachment parts.
• Q-Encoding is used for encoding/decoding corresponding MIME message headers now, compare #77 for details
