[8] As a user i want to see sorted and filtered articles

There should be an additional @published [ArticleData], which always contains the data that's displayed in the article list view. When searching or only looking at a certain feed or collection, the list gets emptied, refilled with the fitting articles and sorted by date. Articles of a feed, where the value showInMainFeed is False must not be copied into the main view (all).

To Do

• Create new ArticleData list
• Create viewAll()-Method that empties the list and fills it with all articles from the main storage, where the parent feed showInMainFeed-attribute is True and sort them by date

Acceptance Criteria

• Articles are sorted by date at all times
