There is a distinction between packages which are already installed on the local machine and packages which are available on the remote server. Even with this difference it is important that they are handled the same and can be reused in the same GUI elements. In order to reduce code duplication I created a parent object PackageList which contains the base logic and interface for the QML and let both RemotePackageList and LocalPackageList inherit from this. UX specified that the gear icon (Settings.svg) should be separate from the tabs of material and plugins. This also ment that the current tab item couldn't set the pageTitle anymore. This is now defined in the Package component and set when the loader has loaded the external QML file. Contributes to CURA-8558
