addToast
Displays @toast.
Only one toast can be shown at a time; if a toast is already being displayed, either @toast or the original toast will be placed in a queue, depending on the priority of @toast. See property@Toast:priority.
If called on a toast that's already displayed, its timeout will be reset.
If called on a toast currently in the queue, the toast will be bumped forward to be shown as soon as possible.
