[Florian Müllner <fmuellner src gnome org>]

commit 2586e431d083b1a93d948aa8be85fc713ee716e9

    theme: Improve button styling
    
    - Move the more generic %button style before %bubble_button to reduce
      ugly overrides.
    - Remove sizing factors from _drawing.scss to reduce ugly !importants.
    - Make the %bubble_button style more consistent.
    - Add missing focus styling to %notification_bubble.
