tauri@1.0.0-beta-rc.2

Prevent “once” events from being able to be called multiple times.
Window::trigger(/*...*/) is now properly pub instead of pub(crate).
Manager::once_global(/*...*/) now returns an EventHandler.
Window::once(/*...*/) now returns an EventHandler.
(internal) event::Listeners::trigger(/*...*/) now handles removing “once” events.

Window and global events can now be nested inside event handlers. They will run as soon as the event handler closure is finished in the order they were called. Previously, calling events inside an event handler would produce a deadlock.

Note: The order that event handlers are called when triggered is still non-deterministic.
