Send multicasts in random order.
...
This should not affect most users, but on large networks it should cause service
announcements to work a lot better. This is the result of a prolonged discussion
with a user about the visibility of game servers on a large network. The old
multicast algorithm was de-facto randomized due to its distributed nature, while
the new algorithm is more deterministic. This will restore some randomization
beyond limit-overflow conditions.
It won't affect small networks at all.

(1) Back off a little on default max multicast limit since 128 is pretty bandwidth heavy, (2) add a little to default multicast rate limit since new MC algo is fairerererer, (3) decided not to involve netconf masters in multicast so take that out of list of who gets LIKEs.
