Tweaking the Task class a bit.

-) setPreemptible now returns the previous state
-) Events may now not have an owner
-) Events may now have a callback (even though it still needs an owner to get into the ev_loop, for these kind of watchers...)

TODO:
-) think about a way to start a watcher without requireing a Task
-) add a few more things in the Tasks unit tests
