[Bug] Timeout for Toast does not work

[p-yukusai]

As stated, when calling toast.rise() it will not pay attention to the int placed on it and it will just be up indefinitely, I bypassed this by making another thread on a timer that will call for it to lower, though perhaps I just have a fundamental misunderstanding of how it works.
Also, I would love the ability to change the icon for the Toast while it's risen, so, for instance, I'm able to place a check icon to let the user know that a certain operation is over, currently toast.setIcon() doesn't allow me to do this :)
