Make broadcast mode work with master server.
I had never completed this. Two things to note: 1. Distribution via broadcast is still disabled by default in the master server. To enable it, see the comment added in 3.mfrisbeed.sh.in. To use broadcast by default in the client, see the comment in rc.frisbee. 2. If you specify broadcast (-b) in either the client or server, then you should use "-m 255.255.255.255". However, this will broadcast to ALL interfaces on the client/server. To limit to a specific interface, also include "-i <interface-IP>". This will tell the client/server to look up that interface and use the subnet broadcast address in place of 255.255.255.255. Since the master server always starts up frisbeed instances with -i, broadcast will always be directed on the server. Since our rc.frisbee script also fires up the client with -i, it will likewise be directed.
