Implement Misskey-style tree view
Now the tree will be always rooted at the highlighted status, and all its ancestors shown linearly on the top. Enhancement: If an ancestor has more than one reply (i.e. it has a child that is not on current status's ancestor chain), we are given a link to root the thread at that status.
