- added address field to Source struct definition to contain the destination address. If this field is left empty the default multicast address is used. - if a unicast address is provided when creating a new Source the daemon looks in the ARP cache to retrieve the corresponding MAC address. If this is not found the daemon tries to connect to echo TCP service of the destination host and looks into the ARP cache up to 3 times and then returns and error. - added RTP address field in the Source creating form of the WebUI. If this field is left empty the default multicast address is used instead. - updated documentation and regression test suite
