Massive commit with various changes. Added user ranks system (no admin interface yet) and ability for users to have custom user titles. Made cron framework accept fractions of hours through floating-point intervals. Modifed ACL editor to use miniPrompt framework for close confirmation box. Made avatar system use a special page as opposed to fetching the files directly for caching reasons.

echo '<p>The administrator has flagged the page "' . htmlspecialchars($_SERVER['REQUEST_URI']) . '" so that it cannot be accessed from the web. Perhaps this is because this is a cache or includes directory and only needs to be accessed by scripts.</p><p>HTTP error: 403 Forbidden</p>';
