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.

The filter affects the URL. So we can't just start a request in the init. We need to request once all of the properties have been set.
We also can't start the request when the filter changes, because there will be more filters and we don't want to start multiple requests. It needs to be manual.

And back to plug-ins when that tab is clicked.
Sadly, linking the content dynamically doesn't seem to work, with a custom property.
