Politeia Censorship: correct comment censorship info

[xaur]

I see 3 issues on Politeia Censorship page.

First, in two places it suggests that proving censorship is possible for comments and up/downvotes, but doesn't tell how to do it.

Second, I believe the bold parts are incorrect:

When a user registers, a cryptographic identity (pub/priv key pair) is created. This cryptographic identity is then used to create a “censorship token” for each user submission (proposal, comment, comment upvote/downvote).

Third, it doesn't describe how comment censorship works differently. From chat, the user does not get a censorship token for comments, comments can be censored from display, but they still remain in the Git repo.
