Allow "Skip detailed view" per feed

[LinAGKar]

Currently, the "Skip detailed view and open article in web browser" setting is global. However, different feeds differ in which setting is best. For a lot of feeds, the detailed view is just the equivalent of a thumbnail, so you have to go to the browser to read them, so having the setting disabled just adds an extra click. For others, you can read the article completely in the detailed view, so either setting is fine. And then there are some where the detailed view is needed. Notably Hacker News, where the link leads to the target article, so there is no way to get to the comments with the setting enabled. So it would be nice if it was possible to set this per feed. Of course, at least in the case of Hacker News, this could also be resolved by allowing access to the element for an item, which there points to the Hacker News comments.
