Add setting to automatically expand taglines

[hjiangsu]

Pull Request Description

This PR adds a new setting under General -> Feed which allows taglines to be automatically expanded. I've also defaulted taglineIsLong to be true as I noticed long taglines cause a weird animation as it transitions from expanded -> collapsed when initially loading the feed.

LGTM!

Something else you could do is change the threshold at which we determine a tagline to be long so that, even without this new setting enabled, people are more likely to see full taglines without having to expand.

I've doubled the height threshold for determining long taglines - ideally, this should translate to seeing at most 2 lines of text before the tagline is considered too long (but won't always be the case due to per-device font sizing).

Let me know if this works!

That sounds good!
