- Removed assets/bbc folder for simplicity, simplified BBC button URLs (i.e. removed the ability to just specify a button name, you'll now have to provide a fully qualified URL), moved bbc/sprite.png to the root (which makes for a shorter URL hardcoded on all pages where you can post), and the textarea resize handle to the buttons folder, because, whatever. (assets/bbc.png, Class-Editor.php, editor.css, sections.css)

- Removed assets/theme folder for simplicity, moved bg.jpg to the root, actions.png to buttons (because that's what they are), and menurow.gif to the same, because, again, whatever. (assets/theme, Wilde/extra.css, Wine/extra.css, Wuthering/extra.css)
* Replaced PNG versions of the language flags with GIF versions. This saves over 1.2KB of gzipped data, for very similar results. Seriously, if you can spot the differences, you're good. (And no, I don't want you on my team. Get off my lawn.) (core/languages/Flag.*.png)

* Made it so that if you want to replace them with PNG versions, you still can. i.e., if you want to use the GIF versions on a currently running Wedge board, you'll have to manually remove the PNG files from the language folders. (Subs-Cache.php)
* Similarly, replaced contacts.png with contacts.gif -- it's using the same palette so there is NO difference at all visually, and it saves a hundred bytes. Gosh. PNG may be the winner overall, but GIF really is great at a lot of things on small files. (contacts.*, index.member.css)
