* Moved ExpanableGroup into its own file

* Noti Group: Cull non-visible notifications + don't calc transforms every frame

Makes sure that only visible notifications are allocated and rendered.
Also moves the transforms on size-allocate instead of every frame.
Should improve performance. :)

* Fixed expandable group not re-allocating on scroll

* Fixed floating notifications warning on first map

* Updated uncrustify config

* Added uncrustify GitHub Action

* Formatted all vala files

* Updated vala-lint config

* Initial Action matching class for config added

* Added filtering logic

* Added documentation

* Handle config serialization for notification-action-filter

* Fixed Notification widgets not being disposed of properly

* Fix notifications loading in whole image size instead of scaling it down

* Fixed floating Notifications not being fully destroyed for quick notifications

Queue close from windows animation callback instead of calling it directly; fix null pointer (double cleanup) in certain scenarios (#649)

* update the config.json to be in sync with latest swaync(5) page

Fixes: #641

* set cssPriority to 'user'

The swaync(5) manpage must be changed as well, since it currently says "application" is the default value.

In waybar formatting, adding "{}" only works when adding it before the icon. It breaks when adding it after the icon. This change fixes the snippet in our README, so that if someone copies our snippet, it will be easier to make changes.

* Search by process name when icon is missing

* fix formatting

* fix linting errors

I forgot to set the initial visible state to false, so it would be
visible, even with only one player active

* feat: Choose outputs by name

* Match the full monitor name + serial number like sway does

* Updated documentation
