* A thorough rewrite of the follow_me routine. The total cost is 38 extra gzipped bytes, which is all right. (topic.js)

  ! Fixed error message in IE8 when loading a page; this was due to style.position not accepting dummy values in a DOMReady context. Go figure...
  ! The feature now works properly when resizing your window. Sounds easy, but it wasn't.
  ! Fixed positioning of the first comment in blog posts. It was badly broken.
  ! HOPEFULLY, I've fixed the Chrome bug of infinite heights forever.
  * Faster page initialization times, due to internal optimizations: min-height is no longer used (this was the root of the infinite height problem), .poster divs are no longer touched, and floated divs only get updated when needed.
  * Severe performance improvements on scroll when hardware sticky positioning isn't available (up to 10 times faster). I went ahead and removed most of the jQuery calls, opting for native JS instead. IE6/7 never supported follow_me in the first place, so there weren't too many issues to fix.

@ For the record, follow_me still looks meh in IE10, even though it works fine in IE8. That's because their smooth scrolling gets priority over page reflows. Not my problem, and I don't care enough to check if this was fixed in IE11.
* Made it possible to specify breakLinks on something else than message links, and used that on IP tracking pages, where links may very well be broken. (Profile-View.php, script.js)

@ This is a very old feature I never cared to commit. I figured, it's only a few bytes to script.js, so whatever... Maybe it'll be used elsewhere by someone else, I don't know. If nobody likes it, I can always revert.
! Reverting an optimization that broke some board list styles. (Boards.template.php)
- I'm pretty sure that's an outdated rule... Anyone with an iPhone? Can you test whether the board list is broken by this removal? (extra.ios.css)
! Fixed a year-old error in a notification string name... It should end in _text, not _email. The French version was correct, but the English (and subsequently German) ones weren't. (Notifications.english.php)
! The recent Wess rewrite (adding the ability to mix regular CSS with indented CSS) broke the @replace feature. (Class-CSS.php)
! I visited Wedge.org on an old Powerbook using Safari 5.1, and it couldn't get to use the CSS, so I'm guessing Safari 5.1 Mac != Safari 5.1 Windows, and Apple, you suck. So I'm extending the maximum version to 5.1 rather than 5.0, and I'd like for anyone with a more recent Mac to confirm that Wedge.org works fine on Safari 6. I think Safari 7 is safe.
