- The split was only done where it seemed that some parts aren't really
needed, which were mainly headers and gtk-doc.
- Update style to be closer with what's common in nixpkgs.
- Change explicit removal of icon theme cache into including the
hicolor theme.
This should solve many issuses, including:
- show mountable volumes and mount-on-click (in Thunar)
- fix shutdown actions (and don't ask for password anymore)
It doesn't explicitly depend on anything in x-updates,
but AFAIK noone has tested it against master (yet).
Connected to #441.
