util.startup: Add prosody.started promise to easily execute code after startup To avoid a race where server-started fires before the promise function body is run (on next tick), I moved server-started to fire on the next tick, which seems sensible anyway. Errors are logged, I'm not sure if we ought to be doing something more here. I'm sure we'll find out.
