* Moved #greeting up a level. Simpler. (index.template.php, index.member.css)

- Removed some outdated clutter. (Wilder/extra.css, Wuthering/extra.css, extra.rtl.css)
* Actually, some of it wasn't clutter, just outdated, and needed some work. (Wilde/extra.css, Wuthering/extra.css)
- Time to say goodbye to IE6 support, little by little... While I'm trying to keep stuff working on it, I'm just removing cosmetic improvements. If it looks ugly, it's because you deserve it. (pngfix.js, */skin.xml)

* Turned <div class="frame"> into anonymous divs. Why..? Because "#my_id .frame" can break if you have multiple nested frame classes, so it's just better to force skinners to do "#my_id > div". I did say I was dropping official IE6 support anyway... (index.template.php, some CSS files)
- Removed the 'reset' class from footers, and hardcoded it into the footer list. Technically, it saves a few bytes of HTML, and even a few of CSS, so... Nothing to lose. (index.template.php, index.css)

- Forgot a .frame in the installer. (install.css)
! Fixed YouTube videos not getting embedded in the gallery if using the https protocol. (Subs-BBC.php)
