theme: Fix sintax error in the theme
theme: rewrite to be structured
- using SASS
- trying to reuse as much of the gtk adwaita as possible
theme: use Adwaita dark style for popup menus

- cannot sue box-shadow sadly.
theme: update some svg assets to adwaita 3.14 counterparts

- switches
- checkboxes
theme: fine tune scrollbars
theme: modal dialogs and tweaked entries
theme: top bar styling.
theme: overview search bar styling
theme: checkboxes
theme: top bar appmenu etc.
theme: volume/mic slider
theme: switches
theme: forgot old overrides of the panel styling
theme: top bar active is underlined.

- glow feels foreign, will be phased out
theme: remove unused assets
theme: overview styling

- still some quirks
- boy is this unstructured mess a pain to clean up :(
theme: workspace pager in overview
theme: entry selections, parsed css
theme: overview-icon fixes
theme: better running, hover and active states for icons

- the active state behaves oddly though, not respecting
  the fill color, just changing alpha it seems...
