Create/update subs works in a basic way
Can delete subs. Only mods see edit links and delete buttons. Better auth errors.
Create/update/delete posts, links to do so only show up to poster
Post urls go to comments if no URL exists
Can post comments
Can delete comments. Only commenter sees edit/delete buttons.
Refactored to use a composite view on the posts Show page, with each comment a subview. Use a global for current_user instead of passing it over and over again.
Can edit comments
