+ Added SVG support to Wess. It's not that interesting for now, as it's inefficient at being compressed. I tried storing files without encoding them, but it didn't work for me, unlike some online samples I found. I'll give it a try another day. (Class-CSS.php)

* Changed credits page to my current gravatar and helped balance columns a bit. (Credits.php, Who.template.php)
* As we::$user['data'] may not always hold a variable in it, devs will always have to use !empty() on its variables, so let's just delete empty variables, to save some database space. (Subs.php)

* Moved members.secret_question/secret_answer to members.data, renamed them to a single 'secret' string, separated by a | bar. This needs testing, as the rewrite unfortunately required a lot of changes, but I was adamant on doing it. (Load.php, Profile-Modify.php, Register.php, Reminder.php, Subs-Members.php)

* Moved members.mod_prefs to members.data, renamed it to 'modset'. (ModerationCenter.php, Profile-Modify.php, Report.php, ScheduledTasks.php)

* Moved members.message_labels to members.data, renamed it to 'pmlabs'. (PersonalMessage.php, Subs-Members.php)

- Removed members.new_pm, as hey_pm was pretty much doing the same thing. Moved label updating code block around, to allow for this change. Hopefully, won't break anything. I've never used that feature in my life. (PersonalMessage.php, Subs-Members.php, Subs-Post.php, Subs.php)

* Updated the install and upgrade scripts to account for all of these, and show how background incremental upgrading works. (Upgrade.php, index.php, install.php, install.sql)

* Commenazi. (Profile-Modify.php, script.js)
! Syntax error broke PMs. (PersonalMessage.php)
* Assigning we::$id to the first found $id_member (while waiting for a more accurate result), allowing data unserialize() errors to be attributed to the (hopefully) correct user. (Class-System.php)

! Another error in PMs. (PersonalMessage.php)

! Error when saving profile. (Profile-Modify.php)
! Inverted values in the cache_get_data helper. Oops! (Subs-Cache.php)
