Switch to libadwaita
- Switch main window to AdwWindow
- Rework the prefs to use Adw* widgets for adaptive and more modern styling
- some simplifications (we're at ~1000 lines less then v43.0)
This is on top of !20 (merged).
TODOs (pre or past merging):
-
symbolic icon for Kerberos prefs page -
Use preset values for the Notification page(let's wait for some design rework) -
Improve user visible strings in prefs, some look redundant, others could be more explanatory - done but needs more consistency, let's break as little translatable strings as possible as a start.
