+ Added upgrade tool to Wedge. This will automatically upgrade your database and files to what's currently expected. I'm not exactly sure what to do if two users are simultaneously running the upgrade script, as I'm not versed into multi-tasking, but... Well, if you have a suggestion on the nicest way to prevent that... (index.php, Upgrade.php)

+ Which also means that I can celebrate by upping Wedge's version number from 0.1 to... 1.0, alpha 1. I'm not saying it's usable in production. I'm just saying we're getting closer to that. (index.php, changelog.txt)

+ Added hey_not and hey_pm variables; these flags are set if you have new notifications (or PMs) and you haven't opened the notification popups yet. Basically, they control the notification button colors (orange or gray). (Class-Notification.php, Notifications.php, PersonalMessage.php, Subs-Post.php, Upgrade.php, index.template.php, install.sql)

* Root, source and plugin folders are now checked for existence within index.php, like the rest, rather than the settings file. Settings should only hold settings. (index.php, OriginalFiles.php)

* Tweaked the Settings.php automatically generated at install time. (OriginalFiles.php)

@ Note: you may want to edit your Settings.php file to remove the multiple file_exists tests after "Make sure the paths are correct"... Really, it'll save your server some time.
