- added "sap_mcast_addr" parameter to daemon conguration and WebUI to configure the SAP multicast address used for sending and receiving source announcements - added REST API to retrieve the remote sources collected by the daemon (GET /api/browse/sources) - added Browser tab to the WebUI to visualize info on the available remote sources - added Info function to sources listed in the Sources tab to visualize the associated SDP file - extended daemon regression tests to test the SAP Browser
