APPWTV-32 webinos.app.connectUi.getMediaItemsManager() handles programmatically CRUD operations on the new unified media store. Such store handles all media displayed by the app grouped by category and forwards events to the playlist store, which are just its projections. Therefore all data operation should be performed on the media item store using the mediaItemManager interface
Simplified categories/media types to: 'audio','video' 'image', 'tvchannel', 'app', 'doc'
