Subject: [PATCH] treewide: implement notifications with swaync

Implemented notifications with SwayNotificationCenter, as well as theming using
the custom theme module. Some Waybar code had to be updated too, and was
also simplified in order to be more consistent with the new
SwayNotificationCenter implementation.
