There's two ways of providing graphical sessions now: - `displayManager.session` via. `desktopManager.session` and `windowManager.session` - `displayManager.sessionPackages` `sessionPackages` doesn't make a distinction between desktop and window managers. This makes selecting a session provided by a package using `desktopManager.default` nonsensical. We therefor introduce `displayManager.defaultSession` which can select a session from either `displayManager.session` or `displayManager.sessionPackages`. It will default to `desktopManager.default + windowManager.default` as before. If the dm default is "none" it will select the first provided session from `sessionPackages`.
