Nextcloud: ability to sort files in attach view

[brendan-pike]

As a Snappymail nextcloud user speed is essential in finding the file you want linked or sent.

In the default nextcloud mail app they have the ability to sort by modified which is very helpful in this regard when a folder contains lots of files.

Also, probably unrelated or outside the scope but I wonder if other fast methods could be found, like file name search function inside the attach view, or a new alt-click menu option from the Files area itself, so you just right-click a file and select Email?

The code for the Nextcloud Files dialog is here:

Would be nice if someone with enough time could enhance this.

Also read #569 and https://docs.nextcloud.com/server/18/developer_manual/client_apis/WebDAV/search.html
