This no longer makes sense with tags always at the top,
users can always create their own main list.
After we remove the side navigation, we can remove the tag setting.
Only refresh the feeds that have not been refreshed since their last interval.
This solves the problem where force-stopping the app during a long feed refresh
would start the refresh all over instead of just taking the feeds that were not
refreshed already.
We check the feed id and the item id when removing from favorites.
However, the item ids are unique, so there is no need to check the feed id.
Actually, I have no idea why it was even added there in the first place.
Now that we have users who somehow ended up with a database where
they cannot un-favorite some of the items, removed the check.
Also make sure to clear the favorites table when deleting a feed.
We already added the queue to the auto-download candidates.
Now that auto-download was rewritten to not be a "master switch",
the code is called even if auto-download is turned off for all subscriptions.
This lead to queued episodes being downloaded for users who had auto-download disabled.
Convert the feature to an explicit setting to avoid behavior changes for users.
Also, this implements a setting to auto-download the queue,
which users have requested because they did not know that AntennaPod already does this.
Finally, it should solve user confusion where they automatically add episodes to the queue
but set the auto-download filter to ignore specific episodes.
We used "GROUP BY" without specifying which item in the group to take.
Apparently, SQLite then takes a deterministic item
instead of the first (randomly sorted) item.
93% of our users have an Android version modern enough that the setting is not available there anyway.
From the remaining 7%, probably only a tiny percentage use that setting.
Removing simplifies our code and makes it easier to maintain.
Users had a hard time understanding that automatic deletion and episode cleanup are two different things.
Maybe that is because in German, both got translated to the exact same string.
Now both are next to each other and the titles are updated, so that it hopefully causes less confusion.
