Allow users to hide the "show x hidden replies" bit for muted notes

There is a new settings called "load_muted_replies", on by default, if turned off, it will hide the button

Don't mute notes by the user's own pubkey

The only way to mute a note of your own is either to mute your own npub or that specific event id. If a word is muted and your note contain this word, it won't be hidden.

Hide muted parents in feeds (sometimes a reply to a muted note will show up, just remove it and its parent if the parent is muted)

This one is the most challenging. It should be done in the new NoteReducer.
The NoteReducer currently look for a parent at a depth of 2. If it turns out that the parent at the depth 3 is muted, we won't catch it.
The solution is obviously to loop until no parent is found just to check if one event in the chain is being muted, in which case all downstream event should be hidden. It might have a small performance footprint.

Awaiting your feedback on that last point to implement the needed changes

If it turns out that the parent at the depth 3 is muted, we won't catch it.

That's ok, we don't have to get too crazy, we should just avoid showing immediate descendants of muted notes if we know we've muted the parent. Deep descendants should still be fair game.

Let's put this underneath mute words and call it "Ignore muted content"
