Move code for initializing and handling view extensions to the new class ViewExtensionsFactory. Beside making DolphinView less complex this will allow the column view to share the view extension code instead of (partly) duplicating it as it has been done before.

Currently only the tooltips- and filepreview-handling have been moved into ViewExtensionsFactory, a further cleanup will be done later.
