! Fixing installer crash, hopefully elegantly. (install.php, Class-System.php)

! If a language was stored in the session variable, disabling that language from the admin area would cause problems. (Class-System.php)

@ Testing requested!
! Last minute change caused installer not to try and recognize browser language preferences. (install.php)
! Fixed the ability to access a forum flawlessly through its IP address. (Needs testing with Pretty URLs enabled.) (QueryString.php)
! Wess didn't allow @if tests to evaluate lone variables as boolean if they were set to an empty string (e.g. $window_bg = '', @if $window_bg background: $window_bg @endif didn't work), while 'false' and '0' values worked fine. I like single-byte fixes. (Class-CSS.php)

! Still in Wess, non-math() functions were only allowed to use unit-less parameters, e.g. with $var = 6px, math($var / 3) was allowed, but round(math($var / 3)) wouldn't work because it was parsed to round(2px). It should now properly return '2px'. (Class-CSS.php)
* Also applied previous emptiness fix to @elseif commands. (Class-CSS.php)

! Empty @elseif commands were internally seen as empty strings and explicitly seen as 'true', when I should have set them to 'true' directly, and ensured that an empty string is a no-go. This is more logical. (Class-CSS.php)

+ Wess will now automatically dismiss properties with empty contents. For instance, "background: $bg" no longer needs to be enclosed in an "@if $bg" test to ensure skinners can disable the background. Please note that @if $bg would still be necessary in situations where the property uses the variable but adds something else to it, for instance "background: $bg, $bg2" or something like that. (Class-CSS.php)

@ I've updated my CSS files to reflect this change, but they're not ready for commit right now, so it'll have to wait more.
! Wrong language string. (ModerationCenter.template.php)
! Wow, a CSS typo! Woot! (mana.css)
! Moved topic notifications weren't outputting the proper URL in e-mails. (notifiers/Move.php)
* Moved the credits page's Special Thanks area to the contributors file, shortened the Aeva Media copyright information, all for a shorter forum credits section. (contributors.txt, Credits.php, Who.english.php)

+ The site team section on that page now shows avatars. Wanted to do that for a long time, but... (Credits.php, Who.template.php)
* Moved title icons to the right of titles in the default homepage. I thought it looks better. (Boards.template.php, Home.template.php, Thoughts.template.php)
! Fixes for the menu. The recent rewrite made it impossible to click an area without text, just like in the good old IE days, and I failed to notice it immediately. New method is better anyway, as sub-menu icons are now clickable... (index.template.php, index.css)
* A few tweaks for easier handling of $main_bg and $head_bg variables, or lack thereof. (index.css)

* I miss the brackets around page numbers... Sue me. I only changed them to use normal weights. (index.css)
! I'm not sure this'll work everywhere (it does for me), but I'm trying a fix for menus not reopening when coming back to a previous page. It's also shorter than the previous code, so... Good. (script.js, index.css)
+ Added basic documentation for skin.xml-based skeleton operations. I thought I'd already done that, sorry... (Warm/skin.xml)
* Improvements to the responsive board list layout. This time, it should be close to perfection... (sections.css)
* Wuthering board list gets a bit more simplemachinesque. Also fixed menu height. (Wuthering/extra.css)

! Fixed multi-line linktrees in Wilde. Also fixed menu height. (Wilde/extra.css)
! Pete bug: moderation filters were broken when specifying a 'contains this regex' rule. Hopefully this fixes it. (Subs-Moderation.php)
! Fixed CSS variables again. This time, variables inside @if/@is tests will automatically be surrounded by double quotes, saving you the need to add them. I'll be honest with you, though: (1) @is is untested, (2) this contradicts my latest changes to the system, wherein an @if test could hold an empty parameter, (3) this implies that all variable tests are loosely typed. But it should also, and that's what I've been looking for, allow you to do @if $non_boolean_var tests without trouble. I apologize for the mess, but I have other things on my mind these days, like my baby coming up. (Class-CSS.php)

- As per the previous tweak, $view_junk no longer requires double quotes. (index.css)

! Ah, the joys of CSS precedence... #wedge > div would always trump #header, not the other way around... (index.css)

@ I'd appreciate if someone else could test these changes thoroughly for me. It'll benefit everyone in the long term.
- #greeting doesn't really need styling... I'm leaving the ID in, but removing its styles. (index.member.css, Wilderless/extra.css, Wireless/extra.css)
! Fixed margin between site news and linktree in Wilderless. (Wilderless/extra.css)
