v1.2.2

• Assume 8bit encoding when no content-transfer-encoding is specified in a MIME message.
• Exclude empty address-lists when building a message with MessageBuilder.
• Retrieve a MIME part wit the fetchId 1 correctly.
• ImapClient.idleStart() throws an error when no mailbox is selected.
• MailClient.fetchMessageContents() allows you to specify which media types you want to include with the includedInlineTypes parameter, e.g. final mime = await mailClient.fetchMessageContents(envelopeMime, includedInlineTypes: [MediaToptype.image]);.
• Convenience improvements:
  • Select a mailbox just by it's flag like MailboxFlag.sent with MailClient.selectMailboxByFlag(MailboxFlag) method.
  • Check if an email address contains a personal name with MailAddress.hasPersonalName getter.
