v0.0.36

• Remove spaces between two encoded words in headers
• High level API support for deleting messages and undoing it:
  • Future<MailResponse<DeleteResult>> deleteMessages(
MessageSequence sequence, Mailbox trashMailbox)
  • Future<MailResponse<DeleteResult>> deleteAllMessages(Mailbox mailbox,
{bool expunge})
• Deleted messages are now preferably moved to \Trash folder, when possible.
• Optionally mark a message as seen by setting markAsSeen parameter to true when fetching messages or message contents
  using the high level API, e.g. MailClient.fetchMessageContents(message, markAsSeen: true);
