Improve useability for WebDAV providers like Nextcloud, ownCloud, …
I read the issues explaining, why first level support for providers like Nextcloud was removed in the past (#46 (closed), #157 (closed)).
Without reading documentation, most users will probably not know, that a lot of the providers like Nextcloud are supported by the WebDAV protocol. To make it even easier for users to back up their files, it’d be great if only the Nextcloud URL would need to be entered, and the user is then ask for the the username and password (as it is now).
