Feature Request: Make grouping by folder in "Unread Articles" view optional

• I have read the CONTRIBUTING.md and followed the provided tips

Explain the Problem

First time News App User here. Although I think the behavior is intentional, I propose an option not to sort the articles by modification/creation time in the "Unread articles" view, but to show them in their chronological order of publishing. If I add a new feed, the corresponding articles are shown first even if they are "older" then articles from other Feeds.

Steps to Reproduce

1. Install News App
2. Add some Feeds.
3. Open "Unread articles" view.
4. Add some more Feeds.
5. Open "Unread articles" view and see last added Feeds first.

System Information

• News app version: 0.9.4
• Nextcloud version: 10.0
• PHP version: 5.6.21
• Database and version: MySQL
• Browser and version: Chrome Mac/52
• Distribution and version: CentOS/Apache self hosted, News app installed from Apps panel

Yep, this is a dup of owncloud-archive/news#836 and is a wontfix for now

Problem will also go away after the first round of updates
