Various adjustments, changes, and new snack bars

* They now have an ID, there cannot be more than one with the same ID. This is because it's likely you'll only be interested in information from one snack bar at a time. Having some with outdated information could be annoying.
* They now move from one screen to another (as long as it's from FZMM).
* If the screens are closed, they become HUDs, and the buttons can't be clicked, making them essentially like toasts. However, when you reopen a screen (from FZMM), they become clickable again.
* Moves the button to expand the description to the left of the title.
* Adds the possibility for the description to start expanded.
* Makes the timers more consistent.
* The timer is now multiplied by the Notification Display Time setting (a vanilla option found in accessibility).
