Add some Nextcloud apps like Bookmarks, Calendar, Talk, News and Deck

[jancborchardt]

Nextcloud has additional apps like some mentioned in https://github.com/Atarity/deploy-your-own-saas/blob/master/MostWanted.md:

• Contacts list :card_index: https://github.com/nextcloud/contacts/
• Tasks :clipboard: https://github.com/nextcloud/tasks/
• Video calls server (Talk, already added)
• Notetaking service with sharing: https://github.com/nextcloud/notes/
• Survey monkey: Forms, to be released soon https://github.com/nextcloud/forms/

As well as much more on https://apps.nextcloud.com – but I guess those are fine for a first addition. ;)

Sorry @Atarity, forgot mentioning you. :)

@jancborchardt I've merged that, but some of the apps will be cleared in the future commit. You guys making a great product which is popular enough.

Thanks @Atarity! :) It’s just always strange seeing it relegated to "storage" – but that might be more of an issue with categorization itself and the breadth of services we have. Thanks a lot for the compilation!
