`RPA.Outlook.Application` update/fix `Move Emails` keyword

[mikahanninen]

Parameter email_filter's type has been changed so that it can be given

1. a string email filter (existing functionality)
2. single email (of type MailItem or dictionary representing email)
3. list of MailItems/dictionaries.

Also added parameter mark_as_read which when set True will mark all emails which has been moved as Read (default).
