Adds buttons to insert HTML formatting, and shows a live preview box of what the comment will look like

Works on

On a page with comments, for example a work: In the main menu bar you'll find a new item "Userscripts" with the option "Comment Formatting Buttons". Selecting that will give you the dialog for choosing the buttons that appear on top of comments.

It's inspired by the popular Comment Formatting Options script, but I created my own version from scratch, trying to fix issues I'd noticed and to add some new features.
