Mailbox statistics

A mailbox has its own statistics like number of messages and its size. Data is stored within the structure pop3::mailbox_stat_t and fetched from a server by using the method pop3::statistics. To get the size of a message itself, there is the method pop3::list which can provide size of a single message or of all messages in a mailbox.
