Twitch Addon: Remove chat log ban buttons

Recently twitch updated their modview and changed the user list. This addon removes the "ban" and "timeout button" from the user list and the "ban user" button from the detail view. This addon works without JS and only adds a stylesheet to your moderation view which hides said ban buttons. As the creator of this addon is a moderator himself this addon will be maintained in case twitch changes the selectors for any of these ban buttons.
