Added RootDObjectManager.newInterval() for creating intervals that are

automatically canceled when the omgr is shutdown (they actually cancel
themselves if they fire after the omgr has been shutdown, which stock intervals
also do, but these guys do so quietly because we know they mean to work that
way).

Made use of that new method and the fluent schedule methods in various places.
