provide shortcut for CachedViewModelCellFactory

[manuel-mauky]

The CachedViewModelCellFactory has to be created with a Function as argument that takes a VM
and calls the FluentViewLoader with the given VM as argument.

In some cases this is needed f.e. when a specific loading process needs to be done (like giving a special resourceBundle to the FluentViewLoader).

But in most cases the Function looks the same:

CachedViewModelCellFactory.create(vm -> FluentViewLoader.fxmlView(MyView.class).viewModel(vm).load());

We could provide a shortcut method for these usecases like this:

CachedViewModelCellFactory.createFxmlView(MyView.class);

Internally we can create the function with the given View type. We need to provide two methods: One for FxmlViews and one for JavaViews.
