Caused by "app.config_reload" in the control center. Changing a value,
reloading, and then chaning it again and reloading -> segfault

* Moved control center notifications into its own widget + vexpand config option

* Fixed cc max size not being respected

All the widgets now have the same padding and margins

Makes it easier to override variables like border radius without
recompiling the original SCSS

* Always use the default GTK theme to allow for a more consistent theming experience

* Default to USER CSS priority

* Added --hide-all option

* Use close_all_notifications method instead of while-loop
