When you like a repost, put likes on the entire hierarchy of repost posts recursively

If you like a repost, all posts from the hierarchy will be liked. If you remove a like from a post, likes will be removed from all posts from the hierarchy. I don’t know what the load will be in the case of large hierarchies (for example, 20 posts), but with small hierarchies (5 posts) everything works fine. Fixes #159
