Ability to ignore/block users on the site
After creating the "concealed content" feature, we need to add a feature for hiding individual user's comments/posts on the site if a user has selected to ignore/block them.
Concealed content feature:

Currently users can "block" users - but this only applies to private messages. It may be confusing that blocking private messages is different from "ignoring" users. It might be correct to make it so that "blocking" users would both block their PMs and hide their posts/comments.
We'll need a view, accessible from a user's own user page, for users to check who is on their ignored/blocked list, which would let them remove users from that list.
