+- Renamed `GlobalShortcut::on_all_shortcuts` to `GlobalShortcut::on_shortcuts`
+- Renamed `GlobalShortcut::register_all` to `GlobalShortcut::register_multiple`
+- Changed `GlobalShortcut::unregister_all` behavior to remove all registerd shortcuts.
+- Added `GlobalShortcut::unregister_multiple` to register a list of shortcuts (old behavior of `unregister_all`).
