This owner changes properties periodically so we can test out the PS's handling
of property changes. To execute, run Sugar and then make sure that the D-Bus
address is the one sugar is using (get it from ~/.sugar/default/session.info).
Then run:
build/bin/sugar-presence-service X
where X is a number 1 -> 9 inclusive. It will generate fake buddy info for that
test buddy and then start up a presence service for that buddy, changing a random
property of the buddy every 10 seconds.
