ADV+ per jlevers

ADV+ provides some utilities that can be used with advrider.com, including:

-- A toggle button that, when toggled on, makes only the original thread poster's posts visible for a given thread.
-- A "fix formatting" button that clears up weird formatting from old versions of the site, or users who've chosen to format their threads strangely (different font colors/sizes, emojis that aren't supposed to be there, etc.)

The settings for each thread (author posts only, fix formatting) are saved, so that when you revisit the thread, the fixes will already be applied.
