HTML tags

Here we analyze, which types of HTML tags are allowed inside the content field. Sanitizing fields is desired behavior as seen in Section B.10 of ActivityPub.

Due to firefish using markdown to format their content, the displayed result in the details table can be a bit off, please consult the example.
