XEP-0297 Stanza Forwarding and XEP-0280 Message Carbons and XEP-0297: Stanza Forwarding implementation This patch adds Forwarded.java, a class to wrap messages forwarded from a different entity. A forwarded stanza contains of a Packet and an optional timestamp. WARNING: The current implementation only allows to forward Message packets, as there is no universal way to parse a Packet from SMACK. XEP-0280 Message Carbons implementation This patch adds Carbon.java, a class to wrap the packet extension defined in XEP-0280 to store copies of messages sent to or received by a user to his other client(s). The CarbonManager allows to register XEP-0280 support with the SDM, to enable and disable the feature and to manipulate messages accordingly.
