In the preferences, the user can select preferred content types that should be used for the library search now. The selected content types are shown at the top of the content type combobox (next to the search text slot). The preferred entries remain in the global list of types that can be filtered for.

The change is consided breaking since the preference name for the preferred search and creation types has been changed in the user settings. Therefore, the user has to re-assign the preferred content types settings.

Additionally, the method ContentCreationUtil#getPreferredTypesForCreation() has been moved to PreferredContentUtil#getPreferredTypes().
